Many people and things inspire me, and I think most people will agree that it's a long list. But I will give you a very short glimpse at a few things that I find inspiring.
1: Past Successes
I am driven to repeat my favorite parts
2: Past Failures
I am driven to avoid my least favorite parts
This is the most important one
I could make a really long list though, including my girlfriend, my family, my pets, my teachers, my friends, certain songs and bands, certain artists, certain flavours of ice cream, etc...
Anything can inspire you, it all depends on how you look at it!
(hopefully that thought inspires you...?) :)
