Sometimes all we need is the right input to spark that creativity and then flow with it. It could be a piece of music, a talk, a look at the sky and some sunlight in the eyes or perhaps just a bit of a toke.
The most important thing is go on with what you are doing and not focus too much on the perfection side of it until you have built something that is already significant, at that point you can start to polish it.
