@Tfmonkey that's what my first thought was, then the resentment started to seep in I was truly happy for him and my brain was like yes that's awesome but you only earnt 1/10 of that, then my other side was like "yes but counter argument: he also is working like 140 hours a fortnight"
@VooDooMedic the competition is only with yourself. You should be happy for your friends who are doing well.
Live the life you want and be happy. How others are doing, both better and worse, are irrelevant to you. If your friend was doing worse that you, it wouldn't make you life any better, it would be exactly the same except your friend would be suffering.
So share in the happiness of your friends and stop trying to "win".
