The first 20 hours -- how to learn anything | Josh Kaufman | TEDxCSU

In my experience, it takes around twenty hours of practice to break through the frustration barrier: to go from knowing absolutely nothing about what you’re trying to do to performing noticeably well.

The reason for this is simple: the early parts of the skill acquisition process usually feel harder than they really are. You’re often confused, and you’ll run into unexpected problems and barriers. Instead of giving up when you experience the slightest difficulty, precommitting to twenty hours makes it easier to persist.
