Is it just me, or are there people that try to find ways to bring you down when you are doing well in life?

It just seems like so many people are underhanded and condescending in this world today, and so stuck up. Like nobody can be happy for you anymore. Like when you tell them something awesome (like a job or a new talent) they have to find the things wrong with it, or when they ask you about your goals and you tell them, they say "you'll never do that" or "you're not smart/talented/cool enough to do that, etc. Can't people just be happy for others? Is everyone's goal in life to be better than others and bring others down? What happened to using your brain and talents, rather than underhandedness to make it in this world?
