How to fill up the brain?

It's fifteen minutes to seven in the morning, and i'm struggling to swallow my breakfast. The fried rice that i made, is slightly too dry, making it difficult for the rice to go down my throat. I actually had to wash it down with some coffee.

Taste wise, today's isn't that interesting. Too much pepper. And i don't quite fancy the colour, a little pale-ish for my liking. But what the heck, life's about learning, and experimenting, and of course, filling up an empty stomach!

I think it's quite easy for me to fill up my empty stomach. I eat little, am not quite choosy, and i can cook simple dishes. And so, to cook this fried rice for example, it is not a hassle, merely an experiment of say, taste-creation, ingredients matching, methodology, timing, and others.

It is to fill up an empty brain which i despair. I cant seem to do this as easily as others. I look, see, try to observe, listen, give my 1 cents worth, digest, each time i that i could, but seems like i'm still very lacking in expressing my thoughts, creatively, dynamically, logically, and clearly.

So many things will go through my minds, never taking their numbers. They just come, sit there, and mess up the brain. Occasionally, of course, some of them do give me interesting ideas, but always, there is no clear methods to follow up on that.

I want to be like others that i know too, so confident, speak so well and thoughtfully on their subjects, do things very creatively successful, understands others well enough to share their thoughts.

But how may i do that?
How do you practice being that?
How do you practice on doing those to be like that?
So please, someone, if you know how, share with me, on how to fill up my brain..
This little empty brain.
Thank you.
