Learn from your competitors.
At the end of the day, unless you’re flying to the moon (and even then), there are always people trying to do exactly what you do. This may be upsetting, it may make you feel unoriginal, or you may not even care. But, what you should do is learn from these other people. Being able to analyze other people will allow you to better analyze yourself. Learn what not to do, what to do better, and what you are doing right already.
Anything you can do, I can do better. Only if you know how well the competition does what you do.
