Be pessimistic, sometimes.
I release new products, ranges, software or other stuff quite often, I’m one of those people who has to have 100 projects on the go at any one time.
When I first started out with my own business, every release or every new project was ‘going to change the world’, or at least my small part of it… but one thing you learn when you’re running your own business, is that 90% of your ideas are crap. Really crap… so crap, it probably wasn’t worth having the idea in the first place.
So when you have a new idea for a project, or product, software, photography shoot, marketing method, networking thingy, a plan or anything else… get behind it, and go at it with everything you’ve got, but remember: be pessimistic sometimes.
It will make failing a lot easier to turn into a learning experience… and after all, failure is what eventually makes winners :)
