On numerous occasions, I’ve been approached with queries on how to begin acquiring Data Science skills. Should you dive into a stack of books, enroll in online courses, pursue post-graduate studies, learn from English content or in your native language, or perhaps invest in paid workshops? Or maybe you’re considering self-studying from the plethora of free content available online. Now, there are even more possibilities than there were when I started with Data Science. Even back then, I found myself struggling to make the right decision and find the optimal path.

Data Science
Programming
Personal Finances
Ever thought about the skills you wish you’d learned earlier in life? Wondering which ones are truly paramount? Reflecting on my own experience, I’ve pinpointed three key areas: Data Science, Programming, and Personal Finances. Each field is valuable in its own right. Yet, it’s when they’re combined that things get really interesting. This blend creates a powerful synergy that can greatly enhance both our professional and personal paths. Let’s dig deeper into these skills individually, and then examine the profound impact of integrating them.
