'What do I want out of the last half of my 20's? What will I look back on and be proud of? When I was about 25, I was living in Vancouver with one of many Mr. Wrongs. I made a list of things I wanted to do before I turned 30. It helped me realize that the road I was on was not leading to my desired destination. Some of the things on the list were achieved before 30. Some took me a little longer.
For example, one of the things on the list was "go on stage." There are many stages. Soon after that I became involved in community radio and stayed actively involved for many years (ButterflyEffect). That seemed stagey enough to meet my need for performance.
So good for you for even asking. It's a question worth seriously considering.
