You have to be able to copy execution as well.
I had a discussion with someone yesterday and they were nervous that if they tried a clever marketing technique that a competitor would pop up and do the same. True. But, it is all about execution. Everyone has ideas, some good, some bad. It is about execution.
If you had the attitude that a competitor will come in and copy what you are doing, you are right. But if that attitude stops you from starting something, building something, or expanding something, you will never leave square 1.
Let them copy you. They will.
It is all about exection!
