Taking things apart.
Talking about things.
When an idea pops into
my head and keeps me awake at night, I know I have to
explore it further, no matter how much time it takes. Quite
a few projects are waiting to be finished or to overcome the
next barriers. Some of them I'll never finish. But I like to
dig deep, sometimes off course, and those crazy things I
stumble upon along the way are usually the best bit. I
suppose it's this journey that says the most about me.
