Prevention is always better than cure. If we know that something with the passage of time might become dangerous , then it is better to take a precautionary step to combat the danger.
In fact "Prevention is better than cure" is one of the most common and popular proverbs. Prevention means to avoid and cure means to correct anything that is troublesome or detrimental. Many of us don't stick to the power of prevention until trouble knocks. Troubles or problems can be averted or made mild by prevention. But foolish beleifs sometimes rule the mind of the right thinking people and compel them to follow an unwise advice. Maintaining a healthy lifestyle is healthier , cheaper and happier than curing any critical illness.
If you are a student , then you should study everyday. But generally all the confusion arises when you study only during the exam dates. There is no need to gamble on your success if you do your studies appropriately on time. Similarly , we should go to the doctor immediately and start for treatment , if there are certain visible symptoms of a disease before getting diagnosed with that disease.
No man is perfect and we all commit mistakes. But with the help of prevention , one can avoid many disasters , complexities, confusions and destructions. We can check ourselves from doing something by thinking about the outcome first and then take appropriate action. Every action should be measured carefully because solving the problem will be more time consuming and more painful compared to taking precaution.
