In an instant-on, one-click shopping universe, the idea of sacrifice is pretty alien. When the world might end tomorrow, when you can get what you want now, when debt is easier than ever to go into, why even consider sacrifice?
Because it's the single best way to achieve your goals. Satisfaction now almost always decreases the reserves we have to build an asset for later. Investing in something worth building always requires you to avoid getting what you want today. Sacrifice might mean giving up an expenditure, but it can also be the bold step of having a difficult conversation now instead of later.
Regardless of the goal, sacrifices make it more likely that you'll get there.
The journey toward that worthy goal, though, is a key part of the goal itself. We are never certain we'll reach our goal, one significant reason that so few people persist. But if the journey involves sacrifice, we're paying for that goal, the goal we're never sure to reach, every day.
The act of sacrifice, of foregoing one thing in our journey toward another one, one more generous, virtuous and useful, is actually a little piece of the satisfaction of the goal itself.
If it comes easy, it's not the same.
