I'm not sure if you seek to
1) identify goals which would enable you to improve your sense of humour or
2) brainstorm goals which would enable yout to apply your sense of humor.
My suggestion would be to try writing a lists of things you like to do and go from there. Ideas for what you can do as a related job or business idea may evolve from talking to people about your interests as well.
