I would tell myself:
1. Get to know yourself. Seek truth, not purpose (through experience, travel, relationships, spirituality)
2. Don't do to others what you don't want done to you.
3. Nothing is the way it appears to be.
4. Don't try to be someone you are not. It will destroy your soul. Just because everyone around you is getting married, applying for a job, having children, that doesn't mean that you have to. Don't identify with something you are not. Don't believe your own lies. You are not a "husband", a "boyfriend", a "musician", an "artist", an "entrepreneur".... You are YOU!
5. Whenever someone asks you a question or for your opinion, take at least a 2 second breath before answering. No matter how passionate or knowledgeable you are on the subject.
6. Don't ever desire to be a slave to somebody or to something. Protect your freedom at all costs.
7. Don't look for a purpose, you don't need to have any. Just live life and pay attention to everything and everyone around you, it should keep you ''busy'' enough for a lifetime.
8 Listen to your soul. A lot of things that our sick society considers normal (such as stress, greed, blind confidence, war) are not normal and never should be.
9. If you eat crap, you will feel like crap. Treat your body well otherwise it will get its revenge sooner or later in the same fashion that your family will turn on you (if you are bad for them). Treat your body like family.
10. True slavery is not only allowing someone to control your job, marriage, wealth but allowing someone to control how you feel from the inside (your emotions, your beliefs, your
goals, your values).
