In all you do yea, strive for understanding, you cannot memorize all the syntax in your tech stack, even senior devs still look up command lines from time to time but when you understand, it becomes second nature

The goal is to become a 'Data Engineer' that knows how to build data pipelines for companies. It won't be easy but I'd get there ✌️

By popular demand CTE's win. They are relatively less stressful as opposed to Subqueries but we should know the two just incase the other doesn't work

If you want to become a developer, you have to be willing to give yourself to a relentless life of study because most times, information's are not necessarily stored in one place You might have to read documentations upon documentations

Blogpost upon blogpost Research papers upon research papers Attend online meetings upon online meeting to get what you're looking for. The truth is you only learn and get results when you give yourself to the hard-work

When writing SQL queries, your eyes has to be sharp o Any misuse of a comma can make your query return an error 🥶 Shine your eyes 😳😂

The truth is, you just have to know a programing language to an extent before you can write write technically that's why it's called "Technical writing" it requires some level of proficiency and understanding in a language. In my opinion, it's always going to be a low barrier

In my opinion, it's always going to be a low barrier to entry WHY? not alot of people like programming. Infact, it scares the living daylight out of them but if you can take pain to learn one, I feel it's a way to get your first paid gig before getting a role

See, Tech is a wonderful industry to be in. Do you know why? Well, asides from hunting for jobs you and a couple of buddies can come together to form a "START UP" to solve peoples problems Hope you know that money will always come out

if you can proffer solutions to people's problems It's just what it is The only problem not alot of people like to hear is you have to take pain to learn the required skill which can take hours or months of study I hope you get my point?

Please before you get started with Python, do SQL first Why? Sql means Structured Query Language It teaches you where you need to put a comma, quotation marks, parentheses, in a structured manner You get to understand why code is written in that manner Trust me,
