Inspiration is always from within. When you have the commitment to do something in life, something in the world, give something to the world back, you can draw inspiration from everything and from everybody around you.
You cannot decide, I want to be inspired by so and so. Inspiration is almost a spontaneous thing that happens to you.
You see a child playing and something happens within you. You feel inspired. You see someone doing some good work and you want to do that.
I feel that when you are free from stress, everything can inspire you.
But if you are clogged with stress, even the best of wisdom does not really enter into you.
