I hate that "comparison is the thief of joy" quote. But in this case, comparison being the thief of success works. Just like comparing whatever is going on in your 50 year-old body to what is going on in a 20 year-old body, comparing your current state of success/failure as an artist to someone who has been doing it for decades (or ten minutes) won't ever end well. An audience of 20 year-olds reacts to things differently than an audience of 47 year-olds. If you design products for established adults, fretting that you are not getting the same result as the artist peddling only pink products to 25 year-olds, you are setting yourself up for disaster. By all means watch, observe, and learn, but be careful about setting yourself up with unrealistic comparisons. What works for someone else may not work for you, and what works for you may not work for someone else. First, be true to who you are. Do what you do best and if you see someone else in your same career age bracket doing their thing with better results, try to figure out what that thing is before deciding it just means you suck. Do they interact with people more? Do they post different kinds of photos? Do they share their personal life or are they all business? What can you do differently? Don't just do what they do, re-evaluate what you do that works, what doesn’t, and what you could do differently to get the result you want.
