Summarize a concept that is new to you.

And remember, if something you learnt was a big win for you, then you know where to drop it as well.👇👇🏻👇🏼👇🏽👇🏾👇🏿

CSS * is closer to RegEx . or RegEx + than RegEx *

I'm pretty sure I already knew it, but I had to relearn it the hard way this week.

I learned about the power of LinkedIn and using social media to build community! 🌎 I posted on LinkedIn about being accepted as one of AWS' Community Builders in the data category and in less than a week, my post has been seen by 49,000+ people so far.

It was an especially cool experience because it has prompted a lot of interest from my network, mentors, mentees, and friends who want to know how to get into tech, coding, software engineering, and app development. I'm actually looking to launch a YouTube channel this month because of this. #ThePowerOfContent
