I made a mistake. I’m going to fix it.

You probably already know me as a senior data scientist and a mentor. I have been sharing learning and experiences from my data science journey. The mistake? I started sharing only when I was 3 years into it.

You don’t see the mistakes I made. You never saw the hours I put in. You see a finished product: a senior data scientist. Wouldn’t it have been better if you saw it from the beginning?

But, in my defence, I was scared. What if people don’t find my learnings worth it? What if they figure out I’m a beginner? Who am I to write about this algorithm? I can’t write about it as if I created it. I’d ask so many questions and give in to my fears.

Eventually, I started sharing. I hit publish but told nobody about it. Somehow it was featured on newsletters, and people noticed. I improved significantly, and my readers benefitted too. Based on my experience, now I encourage every beginner learning data science to share whatever little they know.

Practice What You Preach: In Action

I’m heading on a personal development journey, and I want to share the journey with you from the beginning. I am striving to become a better version of my self. Sounds crazy? And cliche?

Sorry, but I have already seen tangible benefits good enough to convince me one really can become a better version of themselves. I know I’m a beginner, and I’ll make mistakes.

As Nelson Mandela famously stated:

“I never lose. I either I win or learn.”

I still have a lot of fears, but let’s face them. The benefits, as I see, are twofold:

  1. It serves as a document for me to later look back on how far I’ve come.
  2. It can inspire you to become a better version of yourself because I was inspired when others did.

If it’s not clear, the data science journey remains my priority. Personal development isn’t a one-off action; it’s a lifestyle change and is necessarily a process. I think these will go hand in hand for anyone.

Here’s what I told myself:

  • Every month, pick one aspect to improve upon.
  • Treat books as the primary source of truth. Rely on well-researched techniques, concepts from books. Read more to improve understanding of the aspect.
  • Put them to practice. More importantly, give it time.
  • Share your experience, learnings and insights.
  • Take it slow. Reflect upon previous months improvements.

The Journey From Scratch

You’ll find updates on my journey, mostly in the form of articles covering all experiments and improvements I make on to my personal life. It’s just taking off, so you get to see the complete picture.
