If you have the right person by your side, 80% of you don't need it. I found my joy here run 3. and they gave me the answer so I can find joy every day after stressful working hours.

By now, after reading your new replies and tinkering with the play snake game I feel I have a basic understanding of how it works. Looking forward to experimenting more to see how I can make it all work.Thanks a bunch to all of you!
