The Temptation between to Toil & to Reward

The temptation to reward first before completing work.
Can't!
Not yet. I can't.
Even so, the temptation to just give up from toiling for nearly a year, with lack of sleep and lack of even a simple weekend break, is so strong.
Study/Work Hard, Play Hard.
Is it worth it?
The temptation to simply take 'rewards' without even bother to toil for it first is so great.
Constant fight. Between the balance of the two.
Right now. No. not really. Constantly throughout our lives.
If we were to take our rewards so easily, too frequently, we always be ordinary. Never able to achieve more than what we can do/be.
If we were to toil forever, too frequently, we will be 'great'. But we will end up loosing the other part of us that makes life worth cherished.

So which is it to be?
Sometimes, I grow sick and tired of this 'little' game. Sometimes, it's just not worth it. And yet sometimes, I can't. It means too much. It means almost like giving up on life itself.
