Hi 
You do very necessary and useful work for everyone, but especially, as you rightly point out, for young people. I hope that many will follow your example. Here you can tell us whatever you want about all those experiences, it will be great to learn from them.
Could you tell us how you found out about Hive? If a friend recommended it to you, it would be good to mention his/her username so he/she knows you posted. Here is some useful information, and I recommend you start exploring the communities I link below.
Tips and information as a Hive newbie here: newbie guide.
Communities you might like that are part of the OCD Communities Incubation Program. Important: read their rules and post in the one that fits your content.
Have a good day!
