“Everything in moderation” is perhaps the worst advice to let govern your life.
The people who have changed & shaped this world were very focused & single-minded individuals. They didn’t moderate the output of their passion, they opened their throttle full-bore and intelligently applied themselves.
If you want to break the status quo, overcome homeostasis, and actually CHANGE yourself, your business, or the world: moderation is your enemy.
Extremism of course has it’s own problems, but I’d rather fail spectacularly than moderate myself into background noise.
