You need money to get money. Money breeds itself.
You need confidence to get confidence. (Less true than above.)
You need experience in the job to get any such job, but the job is the only way to get the experience.
If you are down, you will be pushed (and sometimes kicked) down further merely because you are down. If you are up you will be lifted up further, merely because you are up. (Existential entropy.) E.g. if you are unhappy, you will lose friends, thus making you more unhappy, and vice-versa.
You say you want to do a certain thing, but once you do it you don’t. (You want to remain thinking that you want to do that thing.)
We fantasize about acting out certain desires at night which we would demonstrate against during the day.
We imagine we would or wouldn’t do well in certain future scenarios simply because we fail to imagine all the prerequisites steps to get into that scenario. We imagine a different world with feature A would or wouldn’t work, because we fail to imagine ALL the other necessary feature changes of B, C, etc to get to that world.
Women want novelty (non-security) from their significant others, yet they want security (non-novelty). Men want intimacy (transparency) between themselves and their significant others, yet they want to be mysterious themselves to another mysterious person, an unknown girl.
A guy needs a girl to show her that he isn’t needy.
Babies ruin sex life, but a sex life makes babies.
We wish for a(n element of the) past or future, which if actualized would leave us yearning for yet another past or future.
We wish we had more fortune, which if we had, would eventually be taken for granted. Or we wish we had things like others, but those others wish they had things like still (higher) others. (Infinite hierarchy of envy and comparison)
We say we value honesty in society, but honesty is only either about things out of one’s control or backfires against the honest. We don’t want the truth because we punish the truthbearer (which we would prefer not to do, right?) or are punished by the truth, yet we do want the truth. In Shakespeare’s Othello, Iago is the most honest character existentially, because he brings the protagonists to themselves, yet he is the most mendacious in a moral sense.
You needed the wisdom to prevent the catastrophe, but you needed the catastrophe to gain the wisdom.
