Thanks for sharing your personal history, Tony Montana. It's reassuring to hear of when someone came to a point of realizing they were at a dead end yet had the wherewithal to move toward something better and were willing to give up the fruits of often hard-won prior accomplishments. Out of disappointment and hardships one may develop the conviction to work toward something better without knowing if it is possible, and if a change is to be successful there must be a sincere reformulation of the self toward the new goal and there must also be an opportunity. The new self will be happier but I think the thing is to be aware that it is not the new lifestyle you are after. Improving the self is the real business. That alone will ultimately bring lasting satisfaction; money and respect are ok but I loathe a day when I cannot find joy within my own heart and mind, something up to me alone. Changing careers is only one form of this expression.
