These aren't necessarily regrets but things I could have done differently.
I would have been nicer to some folks.
I would have loosened up a little and had a little more fun back in the day.
I would have not locked down into some of the long term relationships I was in.
Started saving and investing at age 10.
I would have married my wife a little sooner and not dated for 5 years.
Started my career in a place other than Birmingham. Maybe Hawaii. Once you anchor yourself in an area it is hard to go anywhere else.
