Being young has its advantages: many mistakes are reversible or can be attributed to poor choices and shrugged off.
But sometimes these poor choices can have a lasting impact on you as you grow older.
People got together on reddit and shared some things they wish they knew when they were in their 20s.
Now, while these are subjective, here's a few mistakes young people are recommended to avoid making:
1. Not brushing your teeth.
When my father passed away, I slept away each night without taking care of myself. I've had so many root canals, removals, and pain because of it - and it only hurts what little self image I have of myself.
When your teeth go, you smile less and hate yourself a little more every day. It just takes so much away from you.
