I choose to be a scientist. Someone who always analyzes life and tweaks it when variables come into play.
To trial and error mean to try and fail. I think that shows a lot more in your character than to not try at all.
I dread regrets. They enter my mind and I want to defend against them. They keep me up late at night. Sometime they enter my unconscious.
I cannot stand sitting around and twiddling my thumb. In a school sitting that may make me seen as having a condition of ADHD, but I see it as initiative.
How will you know what you do not like until you try it?
