Time is free, but it's priceless. You can't own it, but you can use it. You can't keep it, but you can spend it. Once you've lost it you can never get it back. "Time and Tide wait for none" means "no matter how powerful a person is, he cannot stop the passage of time. The value of time cannot be undermined. Life is, but a collection of moments, which we must not waste. A child takes birth as a small baby. A baby grows into a child, child into a teen, a teen into an adult and an adult becomes old. The law of nature is supreme. Time keeps flowing. Human beings, whether like it or not, cannot stop these laws. No one can stop the passage of time. The movement of the water in a river flows forever. All these things are beyond human control. We should make a good use of time. We should perform our duties just at the right moment. Many and varied are our duties and we cannot discharge them well unless we do our duty at the right moment. Some people waste their time by indulging in idle gossips that have no real importance in life. Time is like money. Every day, hour, minute, second is precious 

for us. As we spend money wisely, in the same way our time should be spent very cautiously. For this time management is very essential. A farmer has to harvest his crops on time but if he neglects, the birds will eat those crops or untimely rain may destroy it. A successful man only knows the value of time because he has come up with proper use of time coupled with hard work. So, we should not procrastinate, instead every single second should be used carefully. Then only a person will touch the sky of success.
