Is it normal to be jealous of other people's success?
Yep.Totally normal
Yes, it’s normal to feel jealous when someone else succeeds, especially if you want something similar for yourself. The feeling doesn’t make you a bad person; what matters is how you handle it.
Success can bring up comparison before you’ve had a chance to be gracious about it. You might feel happy for someone and still wish you had what they have—both feelings can be true at once. Lots of people experience this, even if they don’t say it out loud.
Jealousy can also point to something you care about or want to work toward. You don’t have to shame yourself for the feeling, but try not to turn it into resentment or take it out on the person. Let it be a clue about your own goals, not a verdict on your worth.
