(these are in random order)
1. making people happy- for example, today at work i completed a project for a client and he called me up and told me how much he loves it and that made my day!! i love doing things for people and seeing their pleased reactions.
2. the feeling when something suddenly clicks and everything becomes crystal clear- this applies in Torah learning but also in secular studies... whenever i don't understand something and then i find another way to explain it that i really like or when someone gives me a new piece of information to complete the picture.
3. driving!
4. singing and music- i've discussed this before :-)
5. hanging out with close friends and just shmoozing and having fun
6. swimming and anything to do with water
7. fave foods, well a few of them: sushi (just had an awesome godzilla roll from Sushi Metsuyan), (israeli) iced coffee, coffee ice cream, whipped cream, and corned beef
