Jealousy and envy are our best enemies

We've all had people around us from whom we knew they did not have our best interest at heart. But what we all have to learn, and this is usually and sadly the hard way, is that almost no one has your best interest at heart, at least not sincerely. Let me explain this more clearly because there are various categories here. We all know the jealous kind who isn't even your friend. I'm not addressing these people, we all know to keep away from them. I'm talking about friends. People you trust, but feel like you need to be careful with what information you share with them, maybe because you feel they envy you. These friends could be very nice an fun to hang out with, but as long as you're not doing better than they are, all will be good. As soon as they sense that you are doing better than they are, will it be in a materialistic, career-wise or romantic aspect, they will change their attitude. I notice that their advice and suggestions changes in a way that they belittle you or make it sound ridiculous what you're asking or saying. Maybe you even read in their eyes that they secretly hope you'll fail. Maybe they are ashamed of wishing that.

Sadly there are many of these kind of people. Personally, I don't understand this behavior. I admit I have friends of which I would love to be able to live their lives, but I will never wish them to fail or wish that they wouldn't be happy. I can sincerely say that I wish everyone the best in life. If a friend will get a job I desperately wanted, I will be upset, not at my friend, but at myself that I didn't work harder or that I didn't do something in my past which would've made me get the job. With friends who are living a life I want to be able to live as well, I try to work hard to get there, I try to change my situation so I can get what I want. I ask advise on how they achieved that and then give it a try myself. 

Maybe I'm naive, but I just don't understand why the majority of human beings only feel good about themselves when they compare their own life with others' that haven't achieved as much. This is behavior of the unintelligent and low life in this world, and I am sad that there are so many of these kind. 

So, what do you do to make you feel better about your life?
