The Holy Bible is not a fairy tale, it is life. Read it.
Choices.
Life is a series of choices. Good choices lead to a good life. Bad choices can lead to a bad life if you continue in them. We all make a bad choice sometimes. Counterbalance it with as many good choices as you can to get back on a good path.
Trust God.
Practice love and forgiveness as we are commanded. Don’t let the world make you hard.
Keep your savings private and do not let some narcissistic parent talk you out of them. Parents are supposed to support their children. If they have failed to do that and you’re on your own, you are not responsible for them.
Always be the best you that you can be.
Keep smiling!
Poet Cea 
My advice for myself would be: -Don’t be lazy and study hard. Life will be so much easier if you do it now.
