once you turn 20 you have to fight everyday for the rest of your life to not lose your personality & spirit...bc what once came naturally to you will be exhausted into nothing if you don't actively Try. it's terrifyingly easy to become a lethargic, soulless adult
One thing about adulthood that way too many people learn way too late (and have no choice but to learn the hard way): you have to be deliberate/proactive about everything. For the first time in your life, you can't be passive participant in anything.
