What can I learn right now in 2 minutes that will be useful for the rest of my life?

The power of visualization.\

Let’s take an example. Do the following finger sequence once with your eyes open.

Touch your thumb to forefinger
Touch your thumb to ring finger
Touch your thumb to middle finger
Touch your thumb to pinkey finger.
Now close your eyes and imagine your fingers doing this, without physically moving your fingers. Repeat it 20 times in your mind.

Open your eyes. Now try the sequence with actually moving your fingers.

You’ll find that you can do the finger sequence pretty well, even though you only physically did it once. You’ve learned the sequence without actually physically practicing it, but with the power of your mind.

Why is this?
