1. Never forget, that you have to tame two deamons and make them your pets. Fear and Greed. Work with them, let them work for you, but never ever let them touch you.

2. it is as risky as you make it. If you can not judge if something you are doing is risky, then you probably shouldnt be doing it anyway (e.g.: juggling running chainsaws, wire walking, or trading bitcoin).

3. If ever you feel you are not 100% in control stop. and take a break.

4. read this: http://nakamotoinstitute.org/mempool/dont-panic/ at least once a week.

5. seriously.

good luck.
