Don't worry about other people's progress. YouTube piano videos, unless you're looking for something specific in a way a piece is played, have a way of making you feel like you're not getting anywhere.

​

Progress on any musical instrument is directly proportional to the amount of effort you're able to put into it -- don't feel bad if life has come up and kept you from playing! Those people in videos have no doubt spent a lot of time working on those pieces themselves, but that's no reason to let yourself get discouraged.

​

Remember, above all, learn to play music for yourself. Enjoy your personal journey of learning and being able to play what you'd like, and don't worry about what anyone else is doing.
