Crafter's Block

Like writer's block, there must be a crafter's block too, otherwise why I am feeling like doing nothing. I have had many ideas lately, but I have one great weakness, If I start the moment I get an idea, I can hope my work will be finished. But if I put it for later then all the creativity and inspiration is gone. Often it so happens that an idea struck and I got to work on it, but this or that material was not available and I had to postpone the implementation. Many of my projects never took off just because of this.
