To be active or not to be active?

Recently wish to join many society
First reason is of course I wish to have more experience
I really think cocu have provide a platform for us to have different experience
However
I always start to active in cocu when other of my friends start to be inactive =.=''

Second reason is due to cocu may help me in writing resume
This is what I knew from my seniors and friends
Cocu is quite important in writing resume...
Hence
I wish to be more active

However
Problem come when I scare I can't balance my academic and cocu
So
Should I be active or not to be active??
It is a question for me.
Sigh~
