If you need to learn/teach object orientation, these are my approaches (I hate that classic "car" example):
1) Keep in mind games like Warcraft, Starcraft, Civilization, Age of Empires (yes, I am old school). They are a good example of having classes to use, instantiating objects (creatures) and putting them to work together. As in a real system.
2) Think of your program as an office that has a job to do, or a factory that has something to deliver. Classes are the roles/jobs and objects are the workers/employees. They don't need to be complex, but their purpose must be really (really, really) well defined. Just like in a real office / factory.
3) Even better (or crazier), see your classes and objects as real beings, digital creatures in a abstract world, and yourself as a kind of god, who creates species (define classes) with wisdom. Give life when it is the time for them to come into the world (instantiate object) and kill them when they are done with their mission (dispose an object). Give them behavior, logic, conditions to work with, situations where they take action, and when they don't. Make them kinda "smart". Build them able to make decisions and take actions based on conditions. Give them life. Think on your program as an ecossystem. There must be balance, connection, species must be well defined and creatures must work together to achieve a common objective. Don't just throw code and pray for it to run. Plan it.

When I talk about my classes like they are real beings, and programs as mini-worlds, some people say I am crazy, some others say that's passion.
It is both! @__@3 -
Dunning-Kruger effect is strong with me.
Thankfully, one of the most important skills that I learned is active listening. I am less vocal about my silly thoughts and shitty opinions these days.
I don't feel dumb. Instead, I realise that I AM dumb.
The people in my new org are exceptionally smart and talented. Each everyone is a hand picked gem. This isn't a coincidence. Rather it's evident that they hire folks very carefully.
In my previous org, I used to be the one driving everything. Like the smartest guy in the room.
But here, I am just quiet in every meeting and I enjoy working 12 hours a day. I am the dumbest guy in the room surrounded by people who are brilliant and humble.
I truly feel fortunate and grateful to be part of such an amazing org and wonderful team. One of the best decisions I made in my career and life.8 -
I don't care about market cap. Stick your hype-driven business practices up your ass. Infinite growth doesn't exist. I won't read your fucking books and attend your fucking bootcamps and MBAs. You don't have a business model. Selling data is not a business model. Fuck your quick-flip venture capital schemes, and especially fuck your “ethics”.
I will be the first alt-tech CEO. I only care about revenue. The real money, not capitalization bubble vaporware. You don't need a huge fleet of engineers if you're smart about your technology, know how to do architecture, and you're not a feature creep. You don't need venture capital if you don't need a huge fleet of engineers. You don't need to sell data if you don't need venture capital. See? See the pattern here?
My experience allows me to build products on entirely my own. I am fully aware of the limitations of being alone, and they only inspire lean thinking and great architectural decisions. If you know throwing capacity at a problem is not an option, you start thinking differently. And if you don't need to hire anyone, it is very easy to turn a profit and make it sustainable.
If you don't follow the path of tech vaporware, you won't have the problems of tech vaporware, namely distrust of your user base, shitty updates that break everything, and of course “oops, they raised capital, time to leave before things go south”.
A friend of mine went the path I'm talking about, developed a product over the course of four years all alone, reached $10k MRR and sold for $0.8M. But I won't sell. I only care about revenue. If I get to $10k MRR, I will most likely stop doing new features and focus on fixing all the bugs there are and improving performance. This and security patches. Maybe an occasional facelift. That's it. Some products are valued because they don't change, like Sublime Text. The utility tool you can rely on. This is my scheme, this is what I want to do in life. A best-kept secret.
Imagine 100 million users that hate my product but use it because there are no alternatives, 100 people in data enrichment department alone, a billion dollars of evaluation (without being profitable), 10 million twitter followers, and ten VC firms telling me what to do and what data to sell.
Fuck that. I'd rather have one thousand loyal customers and $10k MRR. I'm different, some call it a mental illness, but the bottom line is, my goals are beyond their understanding. They call me crazy. I won't say it was never about the money, of course it was, but inflating your evaluation is not “money”. But the only thing they have is their terrible hustle culture lives and some VC street wisdom, meanwhile I HAVE products, it is on record on my PH. I have POTDs, I have a fucking Golden Kitty nomination on health and fitness for a product I made in one day. Fuck you.7
