You are right. But I still find the 'heavier' theory, that is what I assumed OP refered to, to be more difficult to grasp then following a basic tutorial and just trying to solve problems. In time with practice you get a better understanding for WHY the theory is how it is, and you can apply it better and of course improve your code. And that understanding will unlock more tools both in OOP and in your mind.
So if you are struggling, I recommend not starting with theory.
Use it for a while, to complement your theoretical study. Things will only become clearer when you have your own understanding and opinion about it.
I am also convinced that diamonds are a scam. If you like the stone and think it is worth it, by all means, go ahead and buy it. I fucking love shiny things too. But really? Have you seen the price for a tiny 1 karat stone on a ring? That is ridiculous, there is no way in hell those stones are rare enough or warrant that kind of price, and even if the cutting process was the reason for the price ( as if it is not completely fucking automated by now). Fuck the diamond industry.
To be fair. His farming ventures have moved his opinion on climate in a positive direction. People can change their mind and that is a good thing. I would even go as far as calling it a very good sign that even a person as stubborn as the great ape Clarkson can change their opinion on this matter is absolutely fantastic. Good on Clarkson! And fuck the other guy for shoving up the past in his face when he is trying to be better.
