Have fun!

Friday I had a baseball training together with several other 40+ people. I realized that my condition was not that bad and that I really liked the game.
I enjoyed it very much and thinking of making it my second sport activity next to badminton.
When having fun and meeting new people, it stimulates the mind and gives you more than you expect.
Fun in a project at your work is also very important. Sometimes when things are evolving not the way you want it is good to make a joke out of the situation (take into extreme) or/and involve complete new people in the project (for a short term).
The latter is a famous management trick, but it works to keep people alert.
Have fun!
