What Keeps You Going?

I've come to learn that what makes us who we are is what we decide to do differently. Or maybe when we do what are not supposed to do. That longing to push our limits, to dare ourselves. That's what i think make up the most interesting experiences in our lives. That first time we ride a bike, the first time we go behind the steering, that first kiss. These are the most memorable experiences. 

Experiences like these are the hardest to forget because it is at these time that we push boundaries in our lives, we do something new, something we have not dared to do before.
These are what make me want  to keep living my life.That possibility of experiencing new things at some points in my life. These are the things that keep me going? What keeps you going?
