On planks, money, and problems.
If you want less stress at work, think of the absurdity of it all - the hierarchy, the value exchanged (or not), the unspoken rituals and rules.
If you want to make time slow down, do a plank.
If you want less stress about money, think about the context of the global population - you'll go from one of the poorest people you know to one of the richest.
If you want to get mentally tougher, think about the horrid conditions and treatment of countless tortured peoples across time - your task, mental or physical - will seem immensely trivial.
Our problems in life are almost never real, at least not in the way we're seeing them.
Our problems in life are issues of context and framing. We default to our situation being as bad as possible, when logic and reality would show us otherwise.
If you're struggling with something, look for the real. Look for the tangible. Look for the evidence. Test your theories and assumptions you're making about yourself and your situation.
Pause, and reframe it.
