While not particularly novel advice, the one thing I can advise (and I have to remind myself of this constantly) is to be cognizant of whether your spending too much time focusing on the inconsequential things (which seem psychically easier to deal with) than the important things.
In my case, I'm still trying to figure out a plan for getting initial work (which you might imagine is a pretty important thing), but I found myself debating for days about my new logo (which is pretty much guaranteed to never be looked at by anyone for longer than a few seconds at the top of my web page).
I've also spent hours figuring out systems for how I'm going to handle invoicing, client management, output delivery, branding and marketing, etc.
All of those things are certainly important to do, but I find it's way too easy for me to focus my energy on them, instead of the elephant in the room.
Good luck though.
