Wouldn't it be nice if your work stood on its own?
That design, that bit of writing, that piece of craft–what if what you did was judged solely on the merits, if the people engaging with your work saw it for precisely what it was…
Or consider the doctor, able to heal people merely by providing precisely the right treatment on just the right day.
Or the lawyer, winning the case because she presented the most cogent, rational argument.
Doesn't work that way.
The crowd likes the songs from the singer they came to hear, not the unknown opening act. The patient responds to medicine when he believes in the doctor who prescribes it. The client is far more likely to applaud your work if he's already put down a big, non-refundable deposit.
A huge part of making our work more effective is creating the environment where we will be given the benefit of the doubt. Often, creating this environment is at least as important as the work itself.
The benefit to both sides is huge. Doubt is the project killer, and investing in diminishing that doubt is time well spent.
