|You can't push all at once. Use the momentum of the swing, silly!|
Imagine a 2 ton baby giant on a swing, and it is crying at you to push her. You feel obliged since it could possibly crush you with a swat of her arm.
Although difficult, when your hard pushes are timed just right, the giant will begin to swing higher and higher. However, it takes quite a mighty push, and it takes a mighty push at a specific time during the swing. Specifically, on the apex of its back swing.
Learning Something New and Very Difficult
When you are first learning something that is really hard to grasp, it will take a lot of your time. In fact, it better take some of your time every day. Otherwise, you will lose what you've gained.
Say you want to pass a class with an A. That is equivalent to getting the baby giant up to some high level on her swing. Trying to cram everything in the night before the test is like pushing the baby giant to that level with one push. It isn't going to happen.
If we think as each swing forward and back as a day, then we can reach that A level with a timely push every day. Skipping a push, and the giant will quickly lose its momentum and it will take an extra day to get back on track.
A quick review of notes is the equivalent of giving a simple maintenance push, that will keep the giant at her same level. Anything extra, and you can gain a little more toward your goal.
This idea came to me while listening to a similar analogy in Mind Hacking by Sir John Hargrave on my way back and forth to work. I hope it provides an avenue for you to hack your own mind, and perhaps conquer that difficult challenge that looms in front of you.
