How to stop spending your life on people who insist that 1+1=5
"I didn't do anything physical today. Why do I feel destroyed?"
It's the question people ask themselves on the train home, staring out the window. You didn't lift anything. You didn't run anywhere. You sat at a desk, looked at a screen, went to some meetings — and your body feels waterlogged.
We usually diagnose this as a fitness problem and buy vitamins or a gym membership. The actual source is rarely physical. It's emotional leakage — energy escaping through a pipe you didn't know was cracked.
From the moment you wake up, you're in a fight nobody scheduled.
You pour enormous cognitive energy into each of these — proving you're right, or just defending yourself. You draft a reply. You rehearse the comeback in the shower hours later, running the argument again with better lines this time.
Psychology calls that last one rumination, and it's one of the more reliable ways to drain a brain. Susan Nolen-Hoeksema's research established it as a strong predictor of depression and anxiety, not merely a symptom — the repetitive processing itself makes things worse rather than resolving them.
Mental energy is not a free service that refills overnight. It's closer to a battery with a known capacity.
Economics has a word for what matters here: opportunity cost. Energy you spend arguing with someone who was never going to update is borrowed directly from the version of tonight where you study, or have a good conversation with someone you love, or simply rest.
Spending it on people insisting that 1+1=5 is opening your wallet and scattering cash on the pavement.
