What is the difference between Competing and Comparing with others?

In this World there is a lot of Competition. And we should Compete with others. We should always think about how we can do Better and Unique then others.

But in our Life we should never Compare our self with others. If we Compare we will just feel jealous and will just feel depressed. We will just Blame our Life about whatever we are not having.

And especially parents also should never Compare their Children with others or with their own younger or elder Brothers and Sister.

Remember every human being is Unique and everybody has a Value in this World.

So do Competition and not Comparison.
