I've been writing (almost) every day for three years and I'm nowhere close to stopping.
In fact, writing has become such an important part of my daily routine that I feel a little lost when I don't make time for it.
It helps me work through things when I'm stressed out, it allows me to share my thoughts with others, and, most importantly, it gives me a way to practice discipline (something I severely lack).
I honestly believe that if you do something long enough and share it with others, it will eventually lead to bigger opportunities.
Hell, if you ask me, simply becoming a better writer is worth it.
