Write your values
The quality of your life depends on the quality of your decisions.
You make thousands of decisions every day. So you should have a solid foundation on which you can make them.
Write your values. Choose three. Order them and decide why one is more important than the other.
Do everything in your life based on those values.
If something don't follow them, don't do it.
If you have to break one of them, choose the last one. You never break the first of them, no matter what.
Write your values. Follow them.
