I suffer from FOMO all the time!! I have had to condition myself to only compare my results against myself. Usually, most people compare themselves to others who are in situations completely out the their own spectrum.
That could be a good thing for motivation.. But if it has more negative aspects than the positive results you are getting from it, then simply force yourself to ignore it. I actually cover a lot on mindset and how to truly be successful in life in my content. You guys are welcome to let me know your opinions :)
Cheers. Talk soon!
