Work. Be relentless. All over the world, people are working harder than you. Don’t go to events; go to the receptions after the events. If possible, skip the receptions and go to the afterparties, where you can have a real conversation with someone. Money. Learn to live on air. Buy the best health insurance you can afford. If you have roommates, work in the library. Run and do calisthenics instead of paying for a gym membership. Invest in ear plugs, good sneakers, and a coffee machine. Buy oatmeal in bulk. Learn to cook simple, nutritious meals. Save and eat leftovers. Cafes are a waste of money, calories, and time; leave them to the tourists. Buy books used, perform periodic culls, and resell them. Wasting money on clothes is the stupidest habit of all. You will only ever need two good outfits. Health. Stay healthy; sickness is a waste of time and money. Smoking or overeating will eventually make you sick. Drinking and drugs interfere with clear perception, which you will need in order to make good work. It may be worth paying for psychotherapy sessions now instead of paying for inpatient treatment next year; see someone in-network. Friends. Avoid all messy and needy people including family; they threaten your work. You may believe your messy life supplies material, but it in fact distracts you from understanding that material, and until you understand it, it is useless to you. Don’t confuse users, hangers-on, or idols with friends. If a former friend asks you why you don’t have time to see him or her anymore, say your existing responsibilities have made it impossible to socialize as much as you used to. Cutting someone out with no explanation is an insult that will come around.
