That is something that is very common with a lot of people. Filming requires a lot passion and work, organizing sessions, battling the tricks out with the guys (filming shit for 4 hours and ending up empty handed), carrying heavy ass bags. Plus, you got the whole editing process, logging etc.
Im a filmer/photographer and had that happen to me a while back but now I designate days when I go out and film and others just for skating. Filming is sick and very rewarding but it definitely is a bummer when you love skating and have been out almost everyday in the streets yet you were barely able to skate.
