I have already done of good job of eliminating the toxic depressing people in years past, so that is not the problem.
But I now realize there is another type of person who affects how I feel in a negative way: the super-successful advice peddler.
I have recently unfollowed a handful of people on Twitter and LinkedIn who seem perfectly nice, yet give too much advice, or are always acting like they are trying to help me achieve their same level of success.
It feels good so far. It reset my mind so that I can focus on just being myself and forging my own path without worrying about what other people are doing or how I'm not as successful as so-and-so.
So I guess my New Years Resolution is to carry that forward. Do not consume content from people who humble-brag in the form of success advice.
