On (and off) yer bike!
How did you learn to ride a bike? In a classroom? Reading a book? Watching YouTube videos?
No… you got on a bike, tried, fell off, tried again and kept going. Maybe with with a bit of encouragement from someone who can already ride a bike.
This is how you’re going to master your art. Make something, share it, get feedback, figure out what works and doesn’t work, make it again. Keep going until you’re happy with what you’re doing.
