The Feynman Technique
To learn anything:
Step 1: Identify a topic
Step 2: Try to explain it to a 5-year-old
Step 3: Study to fill in knowledge gaps
Step 4: Organize, convey, and review
True genius is the ability to simplify, not complicate.
Simple is beautiful.

Luck Surface Area
👉The amount of luck that will occur in your life, your Luck Surface Area, is directly proportional to what you do something and how much you tell to people .
👉Doing: This refers to the actions you take to create value in the world, such as building a product, writing a book, or starting a business.
👉Telling: This refers to the communication you have with others about what you are doing, such as sharing your ideas, pitching your product, or networking with potential customers.
👉Luck Surface Area: This is the product of doing and telling. The more you do and the more you tell, the larger your luck surface area becomes.
👉Aperture: This is the openness or receptiveness you have to the potential lucky events that come your way.
👉 if you want to create more luck, you should increase your luck surface area by doing more and telling more, and open up your aperture

Software design patterns you MUST know:
🧩 Singleton: One instance per class
🚌 Observer: Monitor & notify object changes
🏭 Factory: Method for creating objects
🌉 Bridge: Decouple abstraction from implementation
🎭 Proxy: Interface representing another object
📚 MVC: Separating application’s logic, UI, and data
⛓ Chain of Resp.: Decentralized request handling
🎈 Prototype: Clone objects for fresh instances
🍂 Composite: Treat individual & group objects uniformly
🖋 Command: Encapsulate request as an object
🎤 Mediator: Centralize external communications
🍦 Decorator: Add responsibilities dynamically
📦 Adapter: Match interfaces of different classes
💼 Strategy: Define interchangeable algorithms
🪄 State: Allow object’s state to change its behavior
🎢 Flyweight: Reuse objects by sharing common data
🌐 Facade: Simplify access to complex subsystems
⚖️ Template: Prescribe method structure in an algorithm
🛡 Proxy: Control access to an object or resource
🌲 Builder: Separate construction & representation
Mastering design patterns: the bridge from novice coder to seasoned developer.
Anything else you have used? What's your favorite pattern?
