How long would it take you to push a car tyre 100 miles?
It’d take you a long time. You’d probably manage to push it 2 or 3 miles before you got tired and had to take a long rest.
It’d probably take you a month to push it 100 miles.
If you recruited 100 people to push the car tyre, it’d take no time at all. Each person pushes the tyre a mile, then passes it on to the next person.
If you recruited 200 people, each person would only need to push that car tyre half a mile.
Each person would only need to put in a short burst of effort to achieve the full 100 miles.
Any large goal is easy when you break it down small enough.
Stop trying to push the car tyre by yourself.
