There will always be someone stronger, better, faster, etc no matter what you do.
With lifting, the best way to think is to count progress. Where did you come from? Say you have a 225lb bench, which some might laugh at, but a year ago you could barely do 135 and a few months ago you were barely able to do 200 cleanly. Many folks in the gym remain stagnant FOREVER and never get anywhere. Likely is the chance that they were relatively strong from the get-go, and never really, truly, earned much in the way of gains.
I've seen that everywhere, you see the guys that look like slugs putting up great numbers, but 3 years later they're still looking and lifting the same. Meanwhile, the "weak" guys who are actually lifting to progress, who have happily enjoyed small but linear gains over time, are catching up to him.
Same goes for guys who lift for size or being lean. One might look good but never get better, while the new guy actually changes his body composition over time and for good. Too many people are proud of basically the way they are naturally and erroneously account that toward their own success. There's a reason most people at any gym will look relatively the same as they always have.
DO NOT let that bug you aside from using it as motivation for yourself.
