dopamine

I’ve read yesterday about the mind functions on how this kind of substance in our brain can affect our mood, motivation and decisions.

Dopamine naturally produced by your brain makes you feel good. You get a rush of dopamine in response to pleasurable activities. On the other hand, without enough dopamine, you may feel sluggish, depressed and uninterested in life. http://www.wikihow.com/Increase-Dopamine

Ever feel emotionally down for no reason? Then, trying your best to know why, by being alone so that you could focus more to what is it all about? Haha. It has also been said that dopamine can also be a big part of a person’s direction in life.

The more times you succeed at something, the longer your brain stores the information that will allow you to do well. That’s because with each success, our brain releases dopamine. When dopamine flows into the brain's reward pathway (the part responsible for pleasure, learning and motivation), we not only feel greater concentration but are inspired to re-experience the activity that caused the chemical release in the first place. http://ph.she.yahoo.com/why-brains-short-term-goals-150000141.html

I wonder what are the things left that most people haven’t know yet, that is actually very important to be included in our general knowledge. I mean, what if all along the humanity isn’t aware in any of this sneaky mind functions that are beyond what we can feel and imagine.

It's like finding out about your birth chart. What if you're a believer of the interpretation of it, but doesn’t really making any sense at all, because there are planets that hasn't been discovered yet. OR;
If you are not a believer of any god and disregards those who do; possibly, someday it will be proven by reason or science in the future. 

widespread acceptance of an idea is not a proof of its validity - D.B

The humanity’s judgement, OUR OWN opinions about other people, beliefs, religion, culture and differences might always just be temporary. 

Whichever kind of reason and rationalizations that agrees with science and latest facts that all of us will have to say, won’t actually be proven/DEFINITE unless everything has all been figured out; which I think will never happen.

No one actually knows best, who's being deceived and who's not regarding diversity. Our safest choice is to be OPEN.

Dopamine is just some of the things in nature that had gave the answer on one mystery of the universe, that the past generation isn’t lucky enough like us to know.

I believe that the world had accomplished a lot since it began... But yet, it’s young; people  are too early (AND always will be) to settle AND CLOSE towards a single belief in a course of a lifetime.
