> "Sometimes I feel like I'm wasting my twenties".

Is near universal to anyone in their twenties regardless of job type/sector. It's the start of most people's adult life, and without the lack of experience that age brings, it's natural to question if you're on the "right path" and/or be swayed by potential other opportunities you've not yet explored.

Hell, even with the experience of age, people still often ask themselves that very same question, and not just for their twenties either.

Exactly, I know people who weren't founders, had a typical college experience and then got a "normal" job that look back and feel as though they wasted their twenties because they didn't grind out some start up. Looking back and wondering if you could've/should've done more/differently is a super common experience.
