I have a 30-day tickler calendar prepared. Each day I remind myself of a couple of activities. I noticed that Hindi was listed for today, and so I acted.
I did a search for Hindi books online. I found plenty at pdfbooks.ourhindi.com and downloaded several. But finally I ended up at Bookbox.com where I listened to a Hindi story.
Years ago, I bought a course and learned the Devanagari alphabet. I might still have known 2 or 3 characters. But as I listened, and followed the subtitles, so many of them came flooding back. They flowed like tears of joy!
