Quote - ...that said, i think it's probably better to make what you love than what everyone else does, because then you're always pleased.   personal fulfillment and happiness aren't the same as success at business.  ...

One of the things I always recommend is "passion."  Be passionate about what you do!  Nobody ever got anywhere as an entrepreneur without passion and succeeding in a very competitive environment is a lot more enjoyable and a lot easier if you are passionate about what you do.

If you don't enjoy your work, your work will reflect that.  If you enjoy your work and are passionate about it, your work will reflect that as well.
