Yes -- read up on what you want to do.
Yes -- listen to the people who have come before you.
Yes -- watch someone else do it and activate your mirror neurons.
BUT -- 90% of your knowledge of doing anything will come from your doing it. Doing it badly. Doing it so terribly you will wonder why you ever started. Doing it 180º different from what you saw on YouTube. It's the way you've always learned -- remember walking and talking? -- Before technology and the easy access to media made you lazy.
Many things in the world have changed. Many things ain't ever changing.
