Does Jealousy have any positive side?

Jealousy is a negative trait. One who is jealous of others should know that Jealousy is an inferno, a big fire that can't be controlled.. Being jealous at  other individual's achievements who are successful will be burnt alive.by their Jealous attitude .One should be tolerant and appreciate the other individual's for their achievements and try to reach their their level by hard work. I do not encourage such self consuming deeds.

No human being is perfect and if some people claim to be so,  they are only fooling themselves. Our creator made us with both positive and negative characteristics which also balances out our personality in its on way. It is only extremes that is bad and need to be curbed since it can become all consuming ..

I feel even jealousy is good provided we use for our improvement and self development and not for tarnishing someone else. And also its good only when it's within in limits... Otherwise it can be harmful to self n society

It all depends upon our attitude. If we are of positive mentality then jealousy can do no harm rather will pose a tough and healthy competition. This calls for an overall progress but when one is jealous and have a negative mindset then it will turn into a major problem. Thus, jealousy is not good or bad but how we look at it and use the various opportunity makes it good or evil.  

Jealousy helps me strive to be better and i take it positively rather than negatively. It helps me bring out the best in me.

Jealousy is a negative trait but we can not deny that it is as natural as any other human emotions. It can not be suppressed and has to be honestly acknowledged. If you keep denying it as negative trait, it keeps haunting you. But once you have acknowledged it, you are ready to introspect and fight against it. And once you fight it and win over it , you will definitely come out with positive. It can spark your hidden ability and even trigger your inner motivation to go ahead and achieve. 

I always feel emotions negative or positive have to be acknowledged and then resolved for a positive outcome.

Jealousy can at times act as a fuel for us to attain some thing.but at the same time it should not cross it's limits.
