We can waste a lot of time and effort in trying to please or sell to everyone. When wondering where to direct your energies, consider the 33% Rule which says that generally, no matter what you do...
33% will like it
33% will hate it
33% won't care
What matters to your success is which group you are catering to. All too often we make the mistake of trying to 'convert' the haters, mostly because we just don't like to not be liked! Invest your time where there is the greatest potential payoff for you. Play the percentages!
