Someone once asked...
Someone answered with kindness...
Experience is something you get when you don't get what you want. Any knowledge you gained will ultimately be useful. Perhaps if you didn't go to college you would regret not investing your time and money in it. It's like ordering the beef and then wishing you ordered the chicken instead. And vice versa. I hope you can release your fear and continue on your journey. There are infinite paths but you will only walk your unique one. You will likely find various opportunities for growth and to unlock your potentional. There is much for you to explore over your lifetime if you live intentionally. Be confident.

I have met people who finished college without being smart enough, and people who couldn't finish it even when they were. College is a lie we make true. But it stays a lie anyway.
