That's a big one too. I got a new job a little over a year ago, but it's a half hour away from my house and requires me to travel through morning rush-hour traffic.

Since I hate traffic and I'm at my most creative in the morning, I simply show up to the office three hours early, make coffee, and write my ass off until I start doing billable work for the company (assuming I don't have other work stuff that's more pressing to do before the day starts). That's been a small workaround for me this past year, but I'm about to eschew that and start going to the gym in the morning instead and simply put up with rush hour for awhile.

Changing up a routine usually helps me find a new stride in the creativity department.
