The fruit of knowledge. "To rediscover the joy of learning."

To rediscover the joy of learning is a broad statement. We could ask ourselves what learning is,  what joy is, we could even go as far as to question if we need to rediscover anything and if we actually haven't forgotten what we learned last time, but all of this is bollocks, just a bunch of wasted text.

To rediscover the joy of learning is as simple as to open your mind.

If you're able to open yourselves up to new ideas, theories, thoughts, physics, imaginative realities and so much more you can find yourself surrounded with thoughts of the wildest things- all found from simply opening your mind, and learning. Everywhere you go there is a lesson to be had, weather it be taking a different route home because there is one light that always takes forever to change, or if it's that your microwave burns popcorn on the popcorn setting so you have to take it out of the over 20 seconds before it says.

What are you interested in?
What do you enjoy doing?
If you don't enjoy doing anything(I call bullshit, but I'll bare with you), what do you enjoy watching?
What do you listen to?
What do you think about?
And last but not lest: Are you a parapoligic?
If you had any answer other than yes on the last one, you're capable of moving around and doing something and if you reference any of the other answers to the 'no, I'm not missing all four of my limbs therefore I'm not entirely disabled' to the 'Are you a parapoligic?' question you will find there is always something to do if you really want to, and once you start doing stuff you'll find pride in accomplishment.

Learning is really a self sustaining process, because it's fed ambition, and produces sustainability.
The learning process if flawless, so why don't you go find something that you can do, progress into finding something you love doing, and then while rediscovering the joy of learning keep it up.
