I love this quote.
There are two parts to it.
You can do anything
This reality of life seems to affect people in one of two ways:
1. The possibilities are endless! How amazing!
2. There are too many choices and I have no idea what to do.
I usually land on the latter.
You can't do everything
I really force myself to look at this one.
Everything I do means trading off something else.
Given that, am I making the right trade offs?
What are the anythings that I really want?
What do I have to trade off in the short run to have those in the long run?
The shorter your horizons are the less choice you have
If my horizon is 30 seconds, there are less choices available to me than if my horizon is 5 minutes.
If my horizon is today, there are less choices available to me than if my horizon is a week.
If my horizon is this year, there are less choices available to me than if my horizon is 10.
Same goes for a decade and a lifetime.
When we feel like we have no choice because we're only looking at this situation, this context, this day, this task, this job, this relationship...because we can't see the life past what we're looking at.
You can do anything but you can't do everything.
