Great article @adsactly. This topic is so important because it enables us to develop mechanisms for protection against experiences which could be overwhelming, it helps us to maintain balance in our lives during difficult or stressful periods of time.
To add to the part you talked about how one can become more resilient, I personally have found that cultivating compassion helps. When I understand that other people are flesh and blood human beings with needs and desires just as valid as mine, I stop seeing them as things in my way or impediments to what I want, and I start thinking more in terms that we're all trying to navigate tricky paths through different and sometimes conflicting needs and we don't have to be dicks about it. The realization that other people have the right to want different things from what I want, and have the right to say no to me, causes me to be more grateful for the times when they say yes. Gratitude is an awesome antidote to entitlement. Entitlement breeds inflexibility and selfishness. Gratitude and compassion breed flexibility and resilience.

At least in my experience.
Great post really. We need this because even as a minnow, i know how many times i was almost down, but i wasnt.
