My wife once asked me how I could practice the same piano piece over and over and over, for hours, without being bored. It seemed to her that I was making a great effort. To me, every time I play, I discover something new, about music, about myself, about the instrument.... Even the least interesting basic exercise piece like Hanon (which roughly corresponds to the sit-up or squatting to build your body), if I concentrate on how every parts of my body works to interact with the piano, it's an unlimited source of discovery. I wish I'd known that when I was younger and taking lessons---I discover how to enjoy practicing long after I stop taking lessons.
Shiro, you are definitely one of the lucky ones. Very few know what it is to do something solely for the joy of doing the thing itself... and the great paradox is that when that is our only motivation, the 'success' that we would have wanted had we been goal (instead of process) orientated comes easy and naturally.
This is how to let the inner spark shine -- allow whatever we choose to do to be it's own reward with no preconditions or ulterior motives. What flows from that is always perfect. And what's more, somehow serendipity starts kicking in.
All great works are created from a sense of joy, not pain. If there is a 'secret' to genius, then surely this is it. Does this help answer your question tyn?
Well, it's certainly inspiring, just a little remark to add: some things are entertaining by nature (e.g. playing soccer) while for other things you need to make an effort (oops, here it is again) to discover the joy in them (e.g. for the procedure of building the right body to play better soccer). Most people will certainly devote more time to the first category of activities (what I've called entertaining by nature).
