> From it I ascertained that the first two questions one should ask are when encountering something in life are, "is this actually important?" and "is this a problem I can actually solve or make a meaningful difference in helping solve?" - anything one can answer "no" to either of those questions one should just let go of, and try to focus one's energies on other problems.

This is also a teaching of stoicism. Focus only on those things you can actually change and understand that your reaction to external things is under your control

“The chief task in life is simply this: to identify and separate matters so that I can say clearly to myself which are externals not under my control, and which have to do with the choices I actually control. Where then do I look for good and evil? Not to uncontrollable externals, but within myself to the choices that are my own…” – Epictetus

“If you are distressed by anything external, the pain is not due to the thing itself, but to your estimate of it; and this you have the power to revoke at any moment.” ― Marcus Aurelius
