In a recent post, Christopher Schwarz takes on the paralysis that comes from perfectionism. At some point, you have to commit to finishing the project in front of you.
One of the best and worst pieces of advice in woodworking goes something like this: Do the very best job that you possibly can.
On the one hand, you get just one shot to build your project. And then you (plus your family or customer) has to live with the furniture until it goes into a museum or the city dump. Of course, when you are first starting out in the craft, getting things perfect can be paralyzing.
