You can't have all you want remaining who you currently are.
Measure the success of your days by the lives touched vs the hours passed.
The excuses we make destroy the results we deserve
You can do whatever you want to do as long as it is correct according to your conscience and heart.
Do your best. And then let life do the rest.
It wasn't until I began to work on my inner life and know myself that my life changed. Success really does begin within. The size and quality of your outer life is only limited by the size and quality of your inner life.
