I personally think it is. From the roots of our Human being we are in the constant search for happiness and in many cases it comes from the enjoyment of what we really like to do or what we really would like to make better. The sense of constant improvement and the attempt to "reach" ideals or dreams are, from my experience, a way to find happiness. Inspiration is a wake up call to help us remember what we think is good, valuable, important and transcendental.
I was checking some minutes ago a web site from Adobe with some neat animations and videos. It is full of material for inspiration. Give a check on it and discover if it motivates your imagination!
