Stop comparing yourself to others. You think that you’re several rungs down on a ladder from them (or several rungs above them) when, in reality, you might not be on the same ladder! If your goals are different from theirs (which everyone’s goals are to a degree) then how can you say that you are ahead of or behind someone?
Comparison is the thief of joy. When you look at others and envy their position, what you often fail to realize is how lucky you are. No matter what your circumstances, you have it better than someone else. Use your past experiences to your advantage. Be ethical about it, understand what privileges you’ve been granted, but don’t feel bad about it.
Be grateful for where you are in life and what you have, but don’t be complacent. Always strive to be better, to help more people, and the results will come. You’re not doing yourself any favors by comparing yourself to others. You can use other people as examples for inspiration or even for what decisions NOT to make, but avoid comparing your actual life to others. What you see on social media is only part of their life.
Finally, remember that you can always learn from anyone – whether they’re older or younger than you, make more/less money than you, have different beliefs/core values, etc. Keep an open mind and remember that even if you disagree with 99% of what they say, if you try to understand their point of view it will open your mind to new ways of thinking.
