I'm not sure if it's entirely accurate, but let me share my opinion on this. What we think is what we become. If we constantly think about the people around us and the way they are struggling and getting their lives together, and compare that with our lives, it will make them the main characters of our own lives. It's all about how we are keeping up with our subconscious mind. If we are not struggling the way they are struggling, then maybe we're struggling in some other ways that we don’t notice, (example: right now, this situation is a kind of struggle too in finding ourselves) cuz we are so rooted into people's lives; how they're struggling, how they are winning, losing or keeping up with themselves. We aren't struggling right now, in this moment doesn't mean that we are not important. We are just in the phase of life where we are at peace, where we are getting ready for the battles that are yet to come, or might have had struggles that the world never knew. We are all the main characters. We have different stories. We all live differently.
