Stoicism for me has been spot on. It helps me in my everyday life immensely.
Once I take the emotion out of the equation I begin to use a part of my brain which hitherto never seemed to exist. My prefrontal cortex. Logic and reason win the day for me. Fears can be driven off , and decision making becomes a doable exercise. Mindfulness is what works for me best.
Staying in the moment. I have to realize too that I have very little control over much of other people and life in general.
Best to all.......
