When you're stuck on a project, walk away to do something for someone else. Getting unstuck on a project isn't rocket science, it's about shifting a view.
When I woke up today I had no idea what I was going to write about. My list of ideas seemed shorter than ever, and none of the topics staring at me through the steam of my coffee seemed worthwhile. Getting unstuck on a project is difficult when we hit that wall.
If you're stuck in a rut, take a step back and go do something for someone else. Don't look for repayment, don't look to have someone indebted to you, just go do something for someone else and stop thinking selfishly for a while.
Maybe it's a making breakfast for the family, maybe it's thank you note, or maybe it's helping a co-worker on a project they are stuck on. Whatever it is, give some time and give some energy and you'll be amazed at how renewed you come back feeling.
When you come back to your personal project, you'll feel refreshed and ready to attack your wall like it was never an obstacle to begin with!
