I'm reminded of the SMBC comic https://www.smbc-comics.com/?id=2722 which resonated with me. If it takes ~7 years to master something, you should dedicate yourself to becoming good at it. Or at least you don't have to tie your identity to what you do you right now; you can reinvent yourself and experience more from of life, but you have to give yourself the time to do so.

It's been almost 14 years since that was published, so maybe some self-reflection is due.
