Terry Pratchett said that ultimately the key to success in life was to be yourself as hard as you can.
Good advice. Frankly, there is a lot of good fiction out there–a LOT of good fiction, and I am constantly amazed at the new voices I read and see as a reviewer for Abyss & Apex, and in our slush. Don’t worry about being better than anyone else; be you. Or, to put it another way, the only thing you can be better at than anyone else is being you.
