Be happy for others' success. Don't compare your life with others. Everyone has their own journey to travel and you never know the battles people fight in their real life compared to the reel life you see on the outside. And they've probably worked hard and gone through tough times to reach where they are or attain what they have. Even if you do compare, you might wish to imbibe the positives from their life, which may help you make wise choices, help you grow or make you a better person. Learn from the good in people's lives.
When a person becomes jealous, it shows his or her own insecurity. When we count our own blessings and our inner resources and work on building our life with faith and confidence, there is no room for jealousy.
