Have Fear
Fear is imporant human trait— it’s what kept your ancestors alive. It’s what keeps you from falling off a building.
When others say “don’t have fear.” What they mean is — assess, plan, understand then move without hesitation. Once risk parameters are defined, THEN don’t let fear keep you isolated.
A healthy level of fear is a good thing, it’s like a tree that gets burned in a forest fire, it doesn’t die, it grows stronger. Nature emulates our own human behavior through plants in we both have extreme ability to adapt.
Being poor, then rich gives you tremendous perspective. Your outlook is everything when it comes to happiness. Stay humble and curious about the world.
