Your 20s are the tutorial phase.
You're fresh out of society's programming. You have the chance to start over, experiment, and explore. The worst thing you can do is stop learning, obey and end up 60 years old with the beliefs of your 20-year-old self.
I despise backup plans
Having a backup plan implies you have a main plan but you're ready to give up if your main plan doesn't work.
Do you really want to live your "back-up" life?
I'd rather die trying to make my main plan work then live a life I don't love.
