18. That effort is more important than intelligence.
As a student with mostly A's or B's throughout school without needing to put much effort into my education I suffered greatly during studies and in my actual job. Most people think I am an under-achiever, which is not completely wrong :/.
19. To say no to things I don't want to do.
20. "Just because you can, doesn't mean you should."
Seriously, I used to use every opportunity that my parents weren't home to smoke weed/mess around and just generally be awful. After I went to school I had that type of freedom all the time. Luckily I had this epiphany before my grades dipped too bad but just because it's possible to do whatever you want at a given moment doesn't mean you should. Learning willpower and motivation as well as self control apparently didn't come until I was an adult but I'm glad I was able to grow up and get my stuff together.
21. Talking to a professional about my mental health. I'm 27yrs old now & just starting talking with a psychologist/life coach. It's a world a difference getting the perspective & advice of a 3rd party not involved in the situation. Wish I did it when I was younger. I would probably be in a different place in life now, but I'm working on where I want to be now.
22. Letting go of anger. You'll have fights with your family, friends, and coworkers. You'll get angry at politicians or ideologies. You'll get angry at something somebody said on Reddit.
But in the end it's all useless. Anger doesn't accomplish anything. I've realized anger is just my own unresolved issues.
23. Guitar. Started teaching myself two months ago and find it to be very relaxing, rewarding and I look forward to playing everyday.
24. Being a compulsive liar and braggart is not only super obvious, but very distasteful. It won't help you be accepted or liked, and will in fact have the opposite effect.
25. Mental health isn't like physical health. if something is wrong mentally, you can't just wait until it's better.
