For those who feel like they're not learning much and feeling demotivated. You should definitely read these lines from one of the book by Andrew Ng 👇

No one can cram everything they need to know over a weekend or even a month. Everyone I
know who’s great at machine learning is a lifelong learner. Given how quickly our field is changing,
there’s little choice but to keep learning if you want to keep up.
How can you maintain a steady pace of learning for years? If you can cultivate the habit of
learning a little bit every week, you can make significant progress with what feels like less effort.

Everyday it gets easier but you need to do it everyday ❤️
