Don't give up
Don't worry about if you're a popular artist or not.
Don't care too much on how people think about you/perceive you.
Always invest in yourself.
Get some quality rest.
Keep friends that are good and healthy.
Don't take any bull from no one. Stand up for yourself if necessary.
Take a step back and deep breathes or utilize other therapeutic devices.
Say no to folks or so called friends when they cross the line.
Include some healthier foods.
Don't worry too much in getting mated or finding a romantic partner. Enjoy singlehood/your own company and appreciate yourself.
Nurture yourself and the shadow self.
It's okay to cry/grieve.
You don't always have to forgive but don't be consumed by anger and resentment. Take time to process them.

And yeah that's pretty much it. Cheers and make the best of your life.
