The barbell theory to life, avoid the middle. For example, with cars don’t buy a V6 engine, either get a 4 cylinder or a V-8.
With investments, don’t do the boring middle risk funds. Rather, either keep boring cash which is super safe, or extremely speculative cryptocurrency investments.
Also with friends and the company you keep, avoid the middle. Avoid your lukewarm friends, and keep your hard-core friends.
