uncertainty
No one actually knows what the hell they’re doing. Everyone is just working off their current best guess.
what is my current best guess and am i living up to it?
certainty
does true certain exist or is it just lack of counterexamples?
Certainty almost never exists and it’s not an excuse to do nothing.
In fact probabilities with very high number in our mind are called certainty, which a mathematician knows in actual world absolute 0 or 1 doesn’t exist. but this doesn’t mean my actions worth nothing. They have a huge impact on everything and they are the parameter in control of ourselves in this big mess.
Probability
Everything in this world has a probability. If I wait to become certain about everything, I can decide about nothing. The key is to be constantly moving based on my current best guess, while constantly reevaluating possibilities and probabilities on the move.
ignored probability (light yagami)
there are times we fail or sth bad happens to us and this is our reponse: but this shouldn’t have happened! this is impossible! i had thought about every small detail! well no, cause you can see that it is actually happened.
Randomness
Does true random exist or is it just lack of information?
Although randomness exists, I can hack my luck and increase or decrease probabilities by my actions.
