Set unrealistic goals when you’re making long-term plans. The realistic and achievable goals are for the day-to-day tasks that drive toward these larger more “unrealistic” goals.
We don’t get excited about the boring, average, and mundane. We get excited about the unrealistic dream.
The point isn’t even to hit that goal, it’s to have a carrot dangling for you to chase and work as hard as you can to get there.
Wherever you end up as a result of this unrealistic goal, it will likely be much better than if you set a “realistic” goal.
