It's kind of like being a writer in the sense that you always hear other writers say, 'Well, the best way to start writing is to just start writing.' The same goes for improvisation. You want to start improvising, just start playing notes. And the more you do that, the more comfortable - or not comfortable - but I guess how you're able to adapt to situations. You become more familiar with your instrument. As soon as you have a musical thought, you can go ahead and add to that musical thought and know your way around.
