This is something I tried before with a Discord group for studying Python, but it was a catastrophic failure. Lots of people showed interest, almost no one showed up at the designated time. Besides, even the one person hardly interacted.

After that, I started creating an online book/tutorial for beginners (well, anyone that is more of a beginner than me :P), but it was hard to stay motivated by myself — the whole reason for the study group was precisely to avoid that.

The topic is not defined yet (I'm thinking logic...), but I'm inclined to try it again. Streaming video and/or audio is a possibility, but not a requirement. I'd rather avoid it if possible.

Any suggestions on how to make this work?

In the simplest terms, I suppose what I'm looking for is just a "quote of the day" generator. Albeit, one that I can put my own quotes into.

I have what I jokingly refer to as an "operating manual". Essentially it's just a constantly-updated evernote that contains rules for how I want to live (eg. "No drinking alone"), reminders about myself (eg. "You always feel better after exercising"), and my philosophy about aspects of life (eg. "In the news media, misery and controversy sell better than joy and harmony").

I'd like to be able to receive bits of this "wisdom" throughout my day, ideally by way of some sort of notification on my phone. Does any such app/service exist? Bonus points for one that is open source and cross-platform!
