"you will have to eternally sacrifice the present for the future"

"We eternally inhabit order, surrounded by chaos. We eternally occupy known territory, surrounded by the unknown.
...
Chaos and order are fundamental elements because every lived situation (even every conceivable lived situation) is made up of both. No matter where we are, there are some things we can identify, make use of, and predict, and some things we neither know nor understand.
...
Living things are always to be found in places they can master, surrounded by things and situations that make them vulnerable. Order is not enough. You can’t just be stable, and secure, and unchanging, because there are still vital and important new things to be learned. Nonetheless, chaos can be too much. You can’t long tolerate being swamped and overwhelmed beyond your capacity to cope while you are learning what you still need to know. Thus, you need to place one foot in what you have mastered and understood and the other in what you are currently exploring and mastering. Then you have positioned yourself where the terror of existence is under control and you are secure, but where you are also alert and engaged.
...
The outside, chaos, always sneaks into the inside, because nothing can be completely walled off from the rest of reality.
...
those who see into the future can also eternally see trouble coming, and must then prepare for all contingencies and possibilities. To do that, you will have to eternally sacrifice the present for the future. You must put aside pleasure for security. In short: you will have to work. And it’s going to be difficult. I hope you’re fond of thorns and thistles, because you’re going to grow a lot of them.”
