If you haven’t been living under a rock for the last 30 years I’m pretty sure you know who Bruce Lee was. 
Here are 7 of my favourite fundamentals from Bruce Lee.
1. What are you really thinking about today?
“As you think, so shall you become.”
2. Simplify.
3. Learn about yourself in interactions.
“To know oneself is to study oneself in action with another person.”
4. Do not divide.
“Take no thought of who is right or wrong or who is better than. Be not for or against.”
“I’m not in this world to live up to your expectations and you’re not in this world to live up to mine.”
6. Be proactive.
“To hell with circumstances; I create opportunities.”
7. Be you.
