Aim for the goal, shoot for the stars and adjust as you go...
Obviously there is need to be in touch with reality, but this statement is meant to rally.
A business in peril that isn’t adjusting… HECK, any business that isn’t adjusting as it goes forward is going to crash and burn. Just because you have a plan doesn’t mean you don’t tweak it. That’s why you don’t plan everything to the ‘Nth” degree before you start moving. You plan enough, but not the whole shebang. You can’t predict everything that’s coming from moment to moment.
Be dynamic. If you approach your business, your launch, your product, your writing, your life in an adjustable way, you’ll have a chance.
