Yes, often I feel better than everyone else, actually, most of us do, but at certain points in our life. The secret to feeling better than everyone or being the happiest person on earth is to stop where we are, then take a step back and look at the things we have achieved or have or have left and try to be stasfied with that , and then again keep going foward!
After that, everyday after waking up, say 'I'm happy with whatever I have at the moment.' Now what if you simply cant feel satisfied with what you have and you feel you want more and more? Well, cant blame you, that is human nature. But the good news is, we dont have to change, we just have to learn to control our temptation.
Although, a wise man once said, 'If there was an automatic ranking for happiest persons on earth, we would have a new winner for the no.1 spot every minute! And thats not a joke, it's a fact!' So, yeah, I feel satisfied with what I have been, that is why I feel better than everyone else, but if that 'person' is right, he sure is, then this feeling is not gonna last for long and it does last for long. One has to be truly satisfied and stay that way for this feeling to be permanent.
