I don't feel guilty for several reasons. I didn't steal or take anything from anyone unfairly; in fact, I didn't do anything "special" that anyone else could not have tried. I didn't come from wealth, in fact from a background that most folks would "assume" would lead to failure. Along the way, I tried to help others. I didn't blame others for the mistakes I made, I just tried to learn from them. I likely could have been much wealthier from a monetary standpoint if my focus had been on getting rich, but my focus was (and is) on doing what I can to help my family and my company.
Certainly good fortune played a part. But I can identify dozens of situations where DW and I did things with money that others laughed at for no other reason than they were impatience and "wanted it all now", and ignored our suggestions for patience. I feel sad for them, but not guilty as it was their choice to do otherwise and end up worse off because of that.
