I celebrate every success. Even if it's just with a fist-pump.
Every published article, every original photo that matches the content of my writing, every book I finish reading, every time I fill a whole notebook.
Every moment I catch myself before I fall into a depressive episode, every time a friend feels they can come to and trust me with something.
I celebrate these things not because I think honoring my goals of 'write every day and be a half- decent human being' are anything special, but because celebration is the pay-off due to success, and even minute successes are important to celebrate.
