Lifestyle: health is part of the edge

Your body is part of the trading desk

Trading is a cognitive job done from a chair, in front of screens, for years. If you do nothing about that physical reality, it eventually breaks you — bad sleep, sore back, dry eyes, headaches, and the slow erosion of the mental sharpness your decisions actually rely on. Career traders don't treat exercise and sleep as 'extras for when you have time.' They treat them as part of the strategy.

Start with sleep. A trader on six hours of broken sleep makes measurably worse decisions than the same trader on eight. Risk assessment drops. Impulse control drops. You'll override your stop loss in a way the well-rested version of you wouldn't. This isn't motivational fluff — your sleep is a risk-management variable. If you're chronically under-slept, you don't have a strategy problem. You have a cognition problem masquerading as a strategy problem.

Next, movement. Two daily walks of 20-30 minutes will do more for your trading than another indicator. They give your eyes a break, get blood out of the chair, and reset your decision-making after a losing session. Pair that with some kind of resistance training a few times a week — your back will thank you when you're still doing this at 50. Posture matters more than you think; a hunched setup leads to neck pain, which leads to shorter sessions, which leads to forced trades to 'make up time.'

Screens are the other quiet enemy. Hours on charts wreck dry eyes and create headaches. The 20-20-20 rule is well-known for a reason: every 20 minutes, look at something 20 feet away for 20 seconds. Keep a glass of water on the desk. Take real breaks, not phone-scrolling breaks. The upside of all of this isn't just feeling better — it's making better decisions for longer, year after year, until you've built a career.

Recap: sleep, walks, resistance training, and screen breaks aren't lifestyle extras. They're cognitive risk management. Build the habits before you build the bigger account.
