Life is what you make it.
It is sad to say, but most things that I do are for my own self interest. Better to ask what is something you have done in someone else's interest. Probably my last was that I gave a hat rack to a dr office. NSA on my part.
I like to keep abreast of the news daily, and I keep a log of what needs to be done weekly and daily so nothing is forgotten. It helps to be organized and to lessen stress.
The only true wisdom is in knowing you know nothing.
