Assuming that it's not just the usual case that you are just starting off, and they have been doing it for years, maybe even decades, assuming that it's a fair apples to apples comparison, and that they actually are superior, do yourself a favour and don't listen to the other advice about it being a "syndrome" (impostor syndrome or otherwise) or some "principle" : own that feeling. Try saying, "Damn, these people are good. And I'm nowhere close to them, not even in the same league".<p>Trust me : acknowledging reality is so, so therapeutic and relaxing that it is a strength by itself. Your anxious mind, previously beset with envy, will suddenly calm down and <i>be able</i> to move on. You will be able to take a deep breath. And then the magic happens : there is an immediate and concentrated focus on the current moment, the reality of being who you are, wherever you are, accepted by every cell of your body. You are <i>so aware</i> of the present moment. In this calm state of assessment, you are already beyond your past feelings of weakness and...and what happens depends, but for me, most of the time, I end up being able to figure out where I can excel and be happy. I am able to ask the Real Questions.<p>While this may sound like a motivational seminar or even a religious one, the reason why it is so generic is that I cannot know what happens after you accept that they are better. I cannot know what exact magic happens. But avoiding the feelings, suppression, is where the problems lie. With psychological suppression, the anxiety never ends. With psychological integration, calmness and health prevail.<p>Us engineers are really bad at this stuff (low EQ), hence so many answers fit the template of avoidance and suppression or worse, false motivation : "you can do it! keep trying!". How do these people know you can? Maybe you suck. You need not conclude that, but you should consider that. May reality be with you!
