Josh Kaufman argues in his talk that it takes 20 hours for you to learn something really well, if you follow these 5 steps:
1. Decide exactly what you want: what is it you are able to do? What does it look like when you are done? What does it look like when you say to yourself that I did this thing I always wanted to do? The more clearly and exactly you are able to define what is it you want to do, the more clearly and completely you are able to define exactly what you want to do, the easier it would be for you to find ways to accomplish that desired result as quickly and efficiently as possible. Defining a target performance level. How well you are able to perform and what does that performance actually look like.
2. Deconstructing skill - all skills are a bundle of skills. You break the global skill into small parts and you practice the most important sub skills - the things you are going to use most, first.
3. Researching - research just enough to identify the sub skills you want to learn. Also understanding and being able to self correct, as you practicing. Find books, courses, people who can help you with the deconstruction. Skim through multiple resources and identify ideas that come up over and over again. Those are the things you should know and you can self correct when you practice.
4. Removing barriers to practice - making it easy to sit down and actually do the things you want to be good at. Making sure you are not distracted by outside forces. Remove distractions and make sure the time is undivided and focused as possible. Anything make it easy for you to do, do that.
5. Pre commit to at least 20 hours deliberate practice.
20 hours ... is a focused, strategic effort invested in something you care about, and something that's going to be rewarding to yourself and to your life.
Repetition is important.
