The devil doesn't need an advocate. The brave need supporters, not critics

The media wants overnight successes (so they have someone to tear down). Ignore them. Ignore the early adopter critics that never have enough to play with. Ignore your investors that want proven tactics and predictable instant results. Listen instead to your real customers, to your vision and make something for the long haul. Because that's how long it's going to take, guys.

Don't try to be the 'next'. Instead, try to be the other, the changer, the new.

Sooner or later, the ones who told you that this isn't the way it's done, the ones who found time to sneer, they will find someone else to hassle. Sooner or later, they stop pointing out how much hubris you've got, how you're not entitled to make a new thing, how you will certainly come to regret your choices. Sooner or later, your work speaks for itself. Outlasting the critics feels like it will take a very long time, but you're more patient than they are.

Go ahead, fail. Try to avoid mistakes, though.

The first step to getting good is admitting that you aren't (yet).

If you're going to invest a valuable asset (like time), go ahead and make it productive. Use a postit or two, or some index cards or a highlighter. Not to write down stuff so you can forget it later, but to create marching orders. It's simple: if three weeks go by and you haven't taken action on what you've written down, you wasted your time.
