The best advice from Seth Godin... ever in my opinion:
“The new thing is never as good as the old thing, at least right now.
Soon, the new thing will be better than the old thing will be. But if you wait until then, it’s going to be too late. Feel free to wax nostalgic about the old thing, but don’t fool yourself into believing it’s going to be here forever. It won’t.”
If you don’t understand this you will have a “KODAK – Moment” and wake up one morning and find that the new thing that was not nearly as good as your old thing has now stolen your business.
