Competition is one of the reason why we gets motivated in doing something. For instance in the business, the company which has no competitors will less trigger to develop their products. It is because that they do know that their customers will only be dependent on their company. Another example is from your school life. Student whom have rival, for rank or score, will be motivated to study harder, while student who does not have rivals will not.
In business, competition leads businesses to lower down their price in order to gain more market share. This will give benefits to the customers since they will gain more choices and have a lower pricing. Moreover, businesses will also develop their products. Therefore, again, competition is beneficial for the customers.
To conclude, competition is a good thing to have. However, remember, things that are too much are not good. Therefore, too much competition will lead to an awful situation.
