There is a thrilling story of two men who were engaged in splitting firewood.
The first man worked all day without a rest.
The second man also worked all day but took off time from time to time to rest.
At the end of the day, the man who took off time to rest did better work than the one who worked continuously without a rest.
When the man who produced better results was questioned on his secret, he said each time he rested, he also sharpened his axe.
The secret of success is work hard but make sure you take off time to rest and sharpen your axe.
There is an old adage which says “All work without play makes Jack a dull boy.”
Hard work is not all that matters. Rest also counts.
