I could notice that many of people coming here because they heard of earning money easily, just trying to promote and spamming with all kinds of things many times.

Well, let me tell You something!

Did you ever question the fact If Aristotle and Plato dedicated their lives to something they don't really believe? Many years ago and still today humans have to learn their Knowledge at the schools. Do you really believe it is meaningless despite the fact we still go so many years back in order to receive the ancient knowledge?
And what I mean by that here and right now is that You have to learn and invest Your time in order to really receive the knowledge of something You want to be successful in. It takes, what they like to call Time to learn and develop certain skills You never tried before. You can be and stay somewhere for decades and still learn nothing.
But, if You really want to invest Your time which is for free to learn something which is for free then You can progress. I, myself, am very impatient many times, but by the time You, I or who ever learn to develop into something bigger but being ignorant and self related all the time. To be understanding, patient and grateful is the key for everyone to grow.
Steemit is the platform that gave You this opportunity and it is totally up to You if You are going to take it or just leave it for no reason at all. Just imagine, there are some great minds behind the curtain trying to connect people in new and improved ways. And You can be a part of the whole story that might change the world we know. Because it is very important thing ! When You touch something and move it, You are the one that made difference. And in difference comes understanding why and that is all that actually matters !
Thank You !
