As they say ''survival of the fittest'' so everyone around us is trying to fit in and trying to prove themselves everyday.
When people get envious that moment we should not let their negativity get into us instead we should be happy celebrating our success. People who can't see others successful often do nothing to harm them but their target gets so affected just by their thoughts that they start harming themselves.

once you're successful there will be people who would envy you because they don't have what you have so treat such people as part of life and rather than getting affected we should move on with ours :)
