His phone rings.
Text messages come flooding in.
Meetings, somehow, are getting squeezed into the limited available time he has.
And in the midst of all that craziness, is the waiting and wondering which player will accept your offer, or which fellow GM will pull the trigger on your proposed trade.
It's become a way of life for Phillies general manager Ruben Amaro Jr. during the offseason.
"If I weren't busy, I'd be worried," Amaro told The Morning Call Tuesday evening.
Amaro's job got even more challenging on Wednesday evening when outfielder B.J. Upton, who the Phillies were trying to woo with the hopes he'd sign a free-agent deal with them, decided to accept the Atlanta Braves' five-year, $75-million offer.
And just in case anyone was wondering if the news was for real, Upton changed his Twitter profile picture to Atlanta's "A" by Wednesday evening.
Are there other free-agent options? Sure. But no one has Amaro particularly enthralled.
"The free-agent market offensively overall is not fantastic, but that doesn't mean that we can't get better," he said.
"We need to have people who can catch the ball. That's a very important part of what we're doing. One thing I did last offseason was get away from that and it hurt us. When we had (Placido Polanco) go down and (Chase) Utley went down and we had (Mike) Fontenot and (Ty Wigginton), they didn't play up to the kind of defense we were accustomed to and it hurt us."
Several outlets still think the Phillies are after Michael Bourn, who turned down the Braves' one-year, $13.3-million qualifying offer recently. But the speedy center fielder also is reportedly entertaining offers from the Washington Nationals and Cincinnati Reds.
Former Phillie Shane Victorino is available, as are Cody Ross and the switch-hitting Angel Pagan.
ESPN.com's Jayson Stark reported about a week ago that several agents who spoke with the Phillies told him that Josh Hamilton is no longer someone they are actively pursuing.
But get this: Jerry Crasnick, who writes for Baseball America and ESPN.com, tells a different story. He wrote on Twitter on Wednesday night that one prominent agent said this to him: "Watch out for (the) Phillies to surprise everyone and sign Hamilton." Crasnick added that a scout told him the same thing.
If the Phillies don't sign any free-agent outfielders or trade for one, Amaro and Co. will be left to make decisions about Darin Ruf, John Mayberry Jr., Nate Schierholtz, Laynce Nix and Dom Brown. Although Ruf impressed everyone with his bat in late September and had a solid winter -- he hit 10 home runs, tying him for the Venezuela Winter League lead and is second in RBIs with 27-- his experience in the outfield is very limited.
"He's at least so far shown us he has the ability to go and play in the outfield, whether he is going to be adequate and not a liability, we don't know yet," Amaro said.
It's safe to say Amaro isn't sold just yet on any of his other in-house options either.
"Domonic made some strides in some areas for us but he's not a finished product either," Amaro said in October. "John Mayberry Jr. got a chance to play quite a bit and at times did rather well and at other times was inconsistent.
"They all have ability. Whether or not they can be everyday players for us, for a championship-caliber club, we're not sure yet."
Amaro also has his work cut out for him at third base. Boston Globe writer Nick Cafardo has reported that the Phils are interested in Kevin Youkilis, who'd bring some much-needed patience at the plate to a team starving for just that.
But if the Indians, Dodgers or Angels, whom Cafardo said are all pursuing Youkilis, win the battle, the Phillies may just have to turn toward a platoon at third with Kevin Frandsen and Freddy Galvis.
Galvis, who made a smooth transition from shortstop to second base on a moment's notice last spring, has spent countless hours this winter in Venezuela working at third base with former Phillies second baseman Manny Trillo, and thus far, the reports are glowing.
"I trust Manny and know him very well. He was one of my coaches," Amaro said Tuesday. "(Galvis) has done very well. I don't have any problem with him playing third base."
If all continues to go well on that front, the Phillies will need Galvis to hit more like he has so far this winter than he did before hurting his back in June. He is hitting .314 with five doubles, two triples, five home runs and 20 RBIs.
Last year, Galvis batted only .226 in 58 regular-season games.
Phils trying to add re liever: In attempt to fill a void that hampered the Phillies for much of the 2012 season, multiple outlets reported on Wednesday afternoon that the Phillies were nearing a deal to make a trade with the Houston Astros. The Phils would acquire RHP Wilton Lopez.
But by Wednesday night, CSN.Philly.com was reporting that the deal was stagnant. The Phillies reportedly had Lopez in town for a physical, something that is usually a technicality. But in Lopez's case, it could truly be a roadblock.
Lopez missed nearly a month in June and July with a sprained ulnar collateral ligament. Many players bounce back from UCL sprains and have no further problems, but it can become serious and eventually tear, an injury that then normally requires Tommy John surgery.
Originally, sources told CSNPhilly.com that the Phillies would give the Astros two upper-level minor leaguers. Rumors were swirling Tuesday that the Phillies had been trying to trade catcher Sebastian Valle, which would open the door for Tommy Joseph to move up to Triple-A Lehigh Valley or possibly be the Phillies' backup catcher until Carlos Ruiz -- suspended for 25 games Tuesday by MLB for testing positive for a banned substance -- returns.
The 29-year-old Lopez was 6-3 with a 2.17 ERA in 64 appearances a season ago. In 661/3 innings pitched, Lopez walked only eight but struck out 54. He allowed 61 hits, four of which were home runs.
Although Lopez ended the year as the Astros' closer after they traded Brett Myers to the White Sox, he is expected to be Philadelphia's setup man for Jonathan Papelbon.
Lopez made $515,000 in 2012 and is arbitration eligible this winter. He can become a free agent after the 2015 season.
