Because practice is also a lot of fun, and even if you can't be perfect, you can enjoy trying and seeing just how close to perfect you can get.
There's no need to be perfect. Developing your skills and progressing is fun though. :)
Ahh, but there are perfect moments. And they are their own rewards.
practice makes you a more well rounded and balanced individual
for the fun of it
trying make us perfect..not quitting
practise make's perfection, not perfect.
