Refresh Yourself with these pleasant thoughts.
I shall pass through this world, but once. If therefore, there is any good that I can do, or if there is any favour that I can show to a fellow human being, let me do it now. Let me not defer or neglect it. For I shall not tread this way again.
IT IS NICE TO BE IMPORTANT BUT ….... BUT IT IS MORE IMPORTANT TO BE NICE
If I give you “My Word” Nobody can undo it. If I sign an “Agreement” my Lawyer will undo it
The trouble with the Rat Race is; Even if you Win you are still a Rat
If you want your work to be done well, then go to a busy man. The other one has no time.
If you pick up a hungry dog and feed it, It will never bite you. That is the principal difference between a dog and a man.
Wise men never sit and cry over their loss. But work on to redress the same.
