no need to..

there is no need to accept every job given to u ..
not all jobs are meant for u.

there is no need to do everything there is to do...

not everything is worth undertaking.

there is no need take others too seriously....

not all of them are serious.

there is no need to take ... yourself too seriously too.

you are nothing compared to the greatest of them all

There is, however, a need to take stock of the things we are doing that are, incidentally, needless..
