It 100% is realistic dependent on the field. If you combine what you learned from YouTube with personal projects you can be professionally proficient in: - An instrument/songwriting - Music Production - Video Production - DevOps - Network Administration - Any kind of programming (Frontend, Backend, Game Development, Assembly, whatever you can think of) - Vehicle Mechanics - Electronics Repair - Maths - Hair and Makeup - Costume/Fashion Design - Fitness/sport coaching - Graphic Design - Bookkeeping - CAD Design - Carpentry - Plumbing And these are just the ones off the top of my head.

Proficiency and reputation trump certificates.
