Describe Lower the Bar here.
Worrying about doing things perfectly will keep you from doing anything.
My major professor had to explain this to me. If you wait to design the perfect experiment, you'll never get into the lab. Better to do something, anything, that will give you some preliminary data and a clue about how to improve the experiment. (If you don't do research, just substitute "recipe" for "experiment" and "kitchen" for "lab".)
A friend of mine has one of those backpack baby carriers, but the buckle broke and she couldn't use it--or afford to get a new one. I have the tools to fix it, and even though my stitching was kind of messy-looking, it worked. She didn't care. She was very happy about being able to carry the baby in the carrier again, and who's going to look at black stitching on a black strap anyhow?
