Daily, hourly basis work and rest cycles are quite important for a good life..

Alternate work and rest cycle should be maintained to be healthy and fit....

Working for a long duration at a stretch is injurious to health and wellness... 

Do some important work, and relax for an equivalent time... Take up your next job and finish it... Then, take rest again... 

In between, do a session of deep meditation... 

Do entertain yourself, when you get free... 

Try to be productive throughout your work hours and also deep thinking period... 

Be at peace with your own self at the end of the day...
