in no particular order
1. Video Gaming
2. Drinking Alcahol
3. Having Fun With Friends (probably should be no.1 as it often combines 1 & 2)

even being an atheist myself I find it somewhat sad that you prefer the active renouncing of god over any of the following:

 - Being close and intimate with your beloved (including, but not only sex)
 - Eating a lovingly prepared meal with a good selection of wines, accompanied by your friends
 - Listening to your favourite music

bubbling under:

 - Reading a good book
 - Doing outdoor sports
 - Beating a challenging videogame 
 - Skinnydipping in a lake after sauna

1. Music (especially Black Sabbath)
