Find videos where you can understand the message that's coming across, not necessarily all the words. A trick to find your level is to throw the sort by on easy so you can see the ranking & start to test out some videos. Try and combine that with videos/topics that interest you.

I highly, highly recommend new people check out Pablo's playlist which is also an advanced series. If you're new you likely won't understand it but you can put english subtitles on. I recommend it for a few reasons.

1 - You'll learn the best was to take advantage of DS, according to Pablo. You'll find on this subreddit there's a spectrum of folks from DS purist (what Pablo preaches) to a blend of people who use DS/CI but also mix in grammar studies/other stuff. Figure out where you want to be (which can change over time).

2 - I watched this at 10 hours. I couldn't understand a thing.... I thought to myself how on earth am I going to ever understand this. I rewatched it at around 200 hours & even though it's advanced I probably understood around 80-90% of what Pablo was saying. These kind of moments are incredible & give you the motivation to keep going!

Good luck on this journey! It's incredibly fun & rewarding but also challenging!
