What's interesting is that I already share most of these regrets, and I am not dying, at least in the traditional sense since we are all dying. I think for the most part, all one can do in life is to just do. Be yourself but stop worrying about what yourself is. Treat any done project, not matter how small, as a good project. Look for little successes like that. And the older I get, the more I realize that relationships matter.
