In my twenties, I had an amazing ability to run at a problem. Long periods of great focus. The only trouble was how frequently I was running in the wrong direction. The gift of aging for me (late 30's) has been the appreciation that an inability to get into flow is usually because I've got buried reservations on a design/approach, and that I need to spend some time trying to surface them.
