If you begin before you think you’re ready, you’ll achieve more success than 95% of others. Why? Because most people are perfectionists who take years to produce a “piece of art” that’s, frankly, mediocre. Their 2nd attempt will be better, their 3rd attempt even more so. But if you never publish your first attempt, you’ll never get there.
