here is my advice to you. take care of your financial needs. engineer your life so that you are stable financially while maintaining the most modest life-style that is comfortable. in other words, get yourself to a point where the practical aspects of life no longer are a problem. no, i never said it was easy. after that, pursue the tangible aspects of success, or pursue anything you want to, without worry. i say that almost nobody said on their death-bed that they regretted not working harder or that they regretted spending too much time enjoying nature, traveling or spending time with the people they loved. use that fact as a guide-line for choosing what to do.
