Day 7: Trading Leetcode for ML (Temporarily)

Source: Dev.to

Small Wins

• Woke up at 11 AM instead of my usual 12 AM. An hour earlier—counting that as progress while fixing my sleep schedule.
• Did a revision problem on LeetCode today, but I’m seriously considering dropping it for a bit. I’m behind on my ML schedule and can’t do everything perfectly; something has to give.

LeetCode vs. Machine Learning

LeetCode is important for interviews and problem‑solving skills, sure. But right now ML is where I need to focus. Sometimes you have to make strategic decisions about what to sacrifice temporarily. I might come back to LeetCode later, or the streak might break—time will tell.

Logistic Regression

Got into logistic regression today and read through examples in the scikit‑learn documentation. I’m trying to actually understand what’s happening under the hood instead of just copying code and hoping it works.

“It’s easy to import a model, fit it to data, and call it done. If you don’t understand what logistic regression is actually doing, how it differs from linear regression, and when to use it, you’re just a code monkey, not someone who actually knows ML.”

I’m thinking about checking out the California housing dataset question tomorrow—maybe, depending on how much I can catch up.

Building in Public

Posted something on LinkedIn today:
LinkedIn post

I didn’t think I’d become the type to post on LinkedIn, but here we are. Building in public means actually being public about it, even on a corporate social network.

Gym

• Trained arms today.
• Tomorrow is leg day, and I’m already not looking forward to it. Leg days are always brutal, but that’s part of the deal—you can’t just train the muscles you like and ignore the ones you don’t.

The same principle applies to learning: you can’t just do the fun parts and skip the fundamentals that feel boring.

Day 7 Summary

Day 7 is done. I’m behind schedule, making tough choices about priorities, but still showing up. Not every day will be perfect; sometimes you’re just trying to minimize damage and keep momentum going.
