First of all, sorry this took nearly a week to reply to. I haven't really ventured out of the RP section for a while.

Ooh... difficult... I haven't really thought about my philosophy on life before...
I think my philosophy on life would be to see life as a big test. It will throw unexpected challenges at us but if we can overcome the obstacles something good will come out of it, whether that be gaining knowledge or skills, becoming a better person, being able to help others with what I've learnt, or maybe something bigger.

I'm hoping that that's what you meant by philosophy... I've never had to use the term before, so excuse me if I got it wrong.
