as much as i love skateboarding, the act itself has rarely, if ever, been a cathartic outlet for me when i'm bummed.
i usually don't skate as much when im bummed. and when i do force myself to skate despite my bumming, i just cruise around and don't enjoy it really.
so yeah, my emotions do affect my session.
i rarely get pissed off or angry. i don't recall an angry session.
the same applies to working out, cycling, or any other physical activity when i'm feeling blue. i'll do it, but i'll just feel the same during and after.
nothing but respect to all those who are capable of letting out their frustrations, pain, and anger or whatever they got during a session or cycling, working out, etc. i always hear it from skaters and read interviews about it.
must be nice!
