The two resources I used all the time were:
Introduction to Real Analysis by Christopher Heil = love this book so much. The author explains everything clearly, guides through the big picture, provides enough intuition and still manage to provide rigorous math.
Video Lectures by Marcus Carlssons = the best lectures you can find on measure theory. The best explanations I could ever find, intuition. His lectures are fun to watch.
Some resources that might be useful¶
Measure Theory by François de Marçay = very rigorous with many visual explanations notes on measure theory.
just some video lectures on measure theory = I didn’t watch it but someone might find that useful.
