It's a decision you have to make. This blog will take me 15 minutes max, to write and post on Twitter and Facebook. What can you do in 15 minutes? You can call an East Coast contact (because it's 10:25 am there). You can email a contact and tell him/her that you're working and you wanted to make the time to see how his dog is feeling, if she got the job she'd been waiting to hear about, or if there's anything you can do to help him/her.
The BEST time to maintain relationships is when you're working because you're not calling to ask for work. So you can full-heartedly make it all about them.
The decision you make is what you have to look at. Are you deciding that you're too tired? Are you deciding you don't have time? Are you deciding that you choose to get immersed in your work and can't get in contact.
OR will you decide that you can find 15 minutes each day to reach out to someone? To get up 15 minutes earlier, reach out for 15 during a long "waiting-period" (you know what I'm talking about), find 15 minutes during lunch, and/or maybe even 15 minutes on your way home if it's a decent hour.
The choice is yours. You've got to decide what you're willing to commit to. My advice- commit to maintaining relationships while you're working (it's what all the cool kids do).
