Learning is driven by surprise, failure, and practice.
Take the time to understand what surprises you properly and deeply enough that it won't surprise you again.
Take the time to understand the root causes of your failures. This will generally not be obvious to you (because if it were obvious, you wouldn't have failed that way).
Take care to practice doing things right -- if you practice doing things wrong, you'll get better at ... doing things wrong.
Now go out, fail in surprising ways frequently, practice being right, and be fruitful. :)
