Another good rule of thumb is to invest in those index funds which average the major businesses because our capitalist overlords will never allow them to fail or not see profit so your only realistic hope for retirement is to ride their coattails. Making individual investment decisions that are consistently contrarian might net you some wins but the consensus opinion will self actualize because they actually control the economy.

Edit: also real estate is rapidly being priced to the point where only massive investment rent collection corps can buy anything, which is already who is buying most of the property in places like London and New York. It’s coming to your town soon too. So get into property if you can and stop giving money to a goddamn landlord as soon as you can before it’s too late to escape that rung of feudalism.
