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.
Just so you can get better. I would rather be okay at something than completely horrible at it.
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.
