The problem with competition is that it takes away the requirement to set your own path, to invent your own method, to find a new way.
Most of your competition spend their days looking forward to those rare moments when everything goes right. Imagine how much leverage you have if you spend your time maximizing those common moments when it doesn't.
Copy, not from your industry, from others. You have to go where there is no competition.
There are lots of good reasons to abandon a project. Having a little competition is not one of them.
Competition and the market are like water, they go where they want
Competition validates you. It creates a category. It permits the sale to be this or that, not yes or no.
The problem with holding a grudge is that your hands are then too full to hold onto anything else. It might be the competition or a technology or the lousy things that someone did a decade ago. None of it is going to get better as a result of revisiting the grudge.
Playing the game is a form of winning the game. In those competitions, we win by being resilient.
The best marketing strategy is to destroy your industry before your competition does.
