I think the hardest part of being a writer is making a live while trying to finding time to write. There are days where I wish I could just take a day off from work, but when those opportunities arrive, I'm usually to tired to even think creativity. I mostly end up sleeping throughout the day or lounging out somewhere doing mindless things.
This fortunately hasn't discouraged me from my passion. I love writing too much to give it up for any price. But it does make it more tricky and a bit frustrating. It's a matter of finding the right balance.
