The saying that practice makes perfect means that after you have plenty of practice in what you are doing you will be perfect in it. He who practices a lot will master the skill more quickly than he who seldom or hardly practices.For example when we learn English we have to learn grammar words expressions and so on.
The most important thing may be how to put what we have learned into practice. If you only learn the grammar rules by heart and don't do enough exercises it is certain that you can't understand them perfectly. But if you practice a lot maybe you will understand them more deeply and you can find some good methods of applying them. Memorizing English words whenever time permitswe can easily memorize them and can even find a way to memorize them more quickly.There is another example. A famous singer can sing very welt.
Of course his talent is very important but practice is necessary. It is necessary to practice to make the singer sing better and better.It is evident that practice is important for everybody. If you want to improve your study and work you should remember that practice makes perfect.
