How can you stop comparing yourself with others?

Well now, aren't you ridiculous for making this comparison.

Anyone can find a bad or good picture of someone, and use it for their purposes, good or bad.

That's the thing about comparisons, they don't, as others gave said, give the whole story.

BTW, to be fair, here's another comparison photo of McKeith & Lawson.
I suppose I could google for images of Lawson alone, and find some bad ones, but what would be the point?

BTW, even in the first photo, McKeither looks fine.

Also, the saying goes:
“When you are content to be simply yourself and don’t compare or compete, everybody will respect you.”
superficially observing these momentary snap-shots observations of others. We can't assume that they're happier or more fulfilled or 'better' people than we are. If we did that, we'd be wasting our valuable time and energy - not to mention that we'd be flat wrong. as we mature and see over and over again that these people aren't as 'perfect' as we thought, we learn to readjust our attitude about the comparing behavior.
