It takes reps to get proficient at anything. You’ve got to put in the effort and practice. Even when it feels like you’re not getting better. Just keep working and you will get better.
Start working now while nobody is looking at you and get your worst work out of the way. In a few years (it’s going to take a few years, yes) when you’re good and people start to notice you, you will have the skills to create amazing artwork, or food, or pictures and get paid for it.
Also, you’ll really enjoy the stuff you’re doing because you know that you’re no fraud. These skills have taken years of practice and preparation to forge.
