Observation is a great way to grow as a writer. I don't have to be surrounded by people all of the time. Something as simple as enjoying a sunset teaches me how to paint a scene that the reader can see in his or her mind's eye. The greatest literary works seem simple, but are incredibly complicated to produce. It takes time to write them.
Much like a tree takes time to grow, with roots and branches spreading out, the writer grows over time. Life is ever changing - hopefully for the better. But even in setbacks, like when a storm breaks off limbs, there are lessons. There are always ways to tweak and get better. The trouble with today is that most people don't want to take time to mature. Those who are willing to work, knowing their weaknesses and striving to strengthen them, are to me, the most successful.
