Find some hobbies:

I joined Toastmasters
Understand what budgeting is. Know where the $$ goes. Make a list of where the $$$$ go. If your incoming $$$ is more than what you spend then you are ahead.
Don't expect your g/f likes you coz you are around more!
Stay healthy or get healthy. See your doc to see if you are healthy. Use that as a base.
Do some travelling. Have some fun. Watch big purchases like cars etc.
Work at staying married. Take a course....
