• What do you really want?
• What do you really value?
• What are you really doing with your life?

Hapiness and success are the alignment of what you want, what you value and what you do. It's called alignment in Buddhism.

How to align?

1. slow down, take a break and only then can your mind become clear.
2. write down who you are and what you value
3. write down what you want
