In case you don't have time to commit to Bobby's well designed course, step-by-step introductions to all the major communication channels available (mostly for free), then just spend a moment with this (out-of-date) YouTube clip.
I dropped out of school in 1964 because I told them they were teaching me stuff that would prove irrelevant to my life (smart-ass kid, getoutofhere) - like, I asked them if I could learn Chinese in the sixth-form (pre-university level school - 16-18 years old - I have no idea what they call that in the USA, China, Japan, India, etc).
I think I might have got something right, even if they considered me a stupid smart-ass kid at the time.
If I could read/write/speak Chinese right now I could have a good job almost anywhere on the planet. Hey ho.
No, I don't have any Chinese (thanks, fellas) but I set out to 'get' internet at the age of 54 (what people who use the Christian calendar vaguely remember as The Millennium, or 2000) and have had a decade of fun - still learning...
