See everything as an opportunity.
This is the thought experiment I wish I could have known in my twenties.
First, start from the negative way to see this world, which we are sometimes succumbed to: this world is full of nonsense; we have to deal with nasty people every day; my job is meaningless.
Now, turn them around: this world is full of wisdom no matter how it seems; we get to help the people who have a problem to solve; my role in a workplace is totally indispensable.
It doesn’t matter whether you truly believe these thoughts or not, because it’s a thought experiment anyway. You just have to pretend as if you believed that way, and reflect on what you would do with that perspective. This is a great way to exercise your creative energy.
