Also wanted to add. I am waiting to hear if the local high school needs a coach for a handball team. I used to play In high school and I coached for a few years as well. I stopped doing it as I felt I was too busy when I really wasn't. Also my boss said I was wasting my time volunteering as its not appreciated, they just use you blah blah. Not sure if he was having a bad day or what cause he is usually great but it made me fear for my job. I don't anymore. If I need to take time off work for something I enjoy then he can suck it up.
I really enjoyed coaching. It felt good to pass on the knowledge I had and watch others grow from it.
The person that you will spend the most time with in your life is yourself, so make yourself as interesting as possible.
