Internet has totally changed my life and for the better. I work from home now and spend most of the day at the computer. I work for organisations all around the world - they send some work by email and then text me to let me know it's waiting. I do the work and send it back. I get paid via Internet banking too. I can work in my pyjammas with a doobie in my hand (though I usually try to hold off on the doob until I've done the work).
If tomorrow there was no Internet? Well, I guess I would go back to what I did for 25 years up until I started my on-line business last year... travelling the world working for universities and other educational institutions. That wasn't bad at all, I can tell you. I saw some wonderful places and met some lovely people. I wouldn't have met my wife if it wasn't for that lifestyle. I only stopped because I'm at the age now where I want to settle down and chill a little. I feel the time zones more when I travel now and an uncomfortable bed leaves me sore the next day.
I'm just mentioning the specifically work-related impact the Internet has had on me, but here I am, sitting chatting to people all over the world on AFN - couldn't have done that a few years back. And all those plant pots and lights and plant food I got off the Internet? And all the information on how to use them? And seeds to!
