You’re 23 - I used to have similar thoughts and beat myself up about it, general anxiety. The right framing (imo) is that your previous behavior is a learning experience that enables you to make the decisions you want now. It’s okay it wasn’t optimal because you’re able to have learned from it and can grow. Ruminating on it is not useful and ignores the growth that came from it. This framing is both true, and generally strategically helpful for not being afraid of failure and trying new things. It also helps coming to peace with “wasted years”. Don’t worry about it basically, focused time will let you catch up and surpass nearly everyone if it’s a goal.
