Why should you feel bad about it? You’re learning from your life experience. I too cringe at stuff I believed before I was mid-30s and married with three kids. I’m also slowly becoming my dad. A lot of that’s due to having seen a lot of things that made me realize my worldview when I was young had been limited. (Freedom of choice and freedom from norms sounds great when you’re young and feel invincible and think you’re in control of your destiny, but less so when you live life and see tons of people making all sorts of bad decisions that you managed to avoid because you did what your square parents told you to do.) That’s life.
