At a deep level , IMHO, the greatest musicians practice so hard because they know what is required of them to express their innner world.
I think many drummers struggle with this: It is easy to use speed as a metric of judgement but I have no time for WFD comptetions. Emotionally how does one express sadness on the drums? or joy? That is what fascinates me.
To dedicate oneself to an art-form requires a good relationship with one's 'self', a sense of quiet certitude that "given x days, y weeks or z years I will get it", and often a willingess to sacrafice short term desires for long term goals...
On a personal note,for example, I know I would love to have a relationship right now but I accept, sometimes with difficulty, that I could not expect a women to put up with the schedule I have at the minute...
