None of us will know if Mark Cuban is truly happy. And we cannot tell for sure if you will ever be happy. What is clear from all you have said, is that riches will not make you happy. You have studied and worked to get where you are. You do not live in isolation so there must be others who have benefited from you being you. I do not doubt your temptation to give up, but I hope you choose to improve. Losing someone who has made such an impact would surely be painful to those you touched.
Though you should not strive solely for wealth, you do not have to refuse that which comes to you. I believe, along the way you can find happiness.
I was captivated by your statement. I am strictly middle class, not very accomplished, not well traveled, not a leader. You seem to have the ability to have an impact which will go beyond the ordinary. I think the effect of your future efforts will be very positive, but I have to admit the chance of failure; your failure and the failure of those who should support your efforts. Including myself.
I made another comment today. Maybe I should keep it up until I learn how to make a difference.
By the way, I like the significance of your login ID. In the long run, that's quite a good sentiment.

Hang in there.
