" Attitude is 100% under your control – (yours to choose, use or lose, as they say)

Happiness, fulfillment and satisfaction in a life ALWAYS and ONLY come as a consequence of some other activity. That is you don’t just create ‘happy’ or ‘satisfied’ – you have to be doing something with your life that as a byproduct creates these states.

That’s it.
Told you it was simple.

Alright, I admit, writing about how to create a ‘successful life’ is easy – because to create something out of your life is 99.9% Mental Focus and 50% ( as Yogi Berra would say and .01% for those of you who are paying attention) -knowing how to get the result and doing it.

Writing about it is easy; it’s the doing that’s hard. "
