I was a thief

I stole several times in the past.
I remember that when I was 5 years old, I stole a rare badge from my kindergarten friend. I remember that possessing possession of this badge did not make me happy because I saw the grief of my friend when she found discovered that the badge was disappeared missing and because I could not show it to anybody.
Then, when I was 19, I took elastics for hair without paying at a chinese market. Even now I am ashamed. I analyzed why I did it. First, I think it is a heritage was characteristic of a soviet times when anything was such things were common, and anybody people took things anything that was misplaced by someone else  «in the wrong place». Secondly, I think  I was not no-one explained to me, with the right words, the reason why to took somebody else’s things taking someone's property without permission was bad. Of course, I was said told that stealing is bad, but I did not felt believe it was bad.
Now that I have children, and I think that I could can find these words for them. I told them that we love our children and children love us and we want to show them signs of our love. We give presents to each other and this makes them happy. Parents work hard to buy a presents to for their children and the children are happy. But sometimes there are thieves, bad thieves who steal the presents,. and I said to asked my children to imagine how those children are unhappy, and perhaps cry perhaps. It is so sad for children and their parents. But thieves are unhappy too. They cannot use stolen things plainly openly because anybody search can see them. But they could be happy if they do not steal, but work and earn money and so they can could buy anything they want.

It could mean any or all of the following depending on context: 1. I'm not meant for... 2. I cannot master the requirements (either technical or knowledge base) of... 3. I'm just no good at..... (usually no matter how I try)

Use the latter since you intend to show the correlation of globalization and the increase access to better education. The first one gives the impression that globalization is a fixed state; it is not,
