I am not a big fan of copyright so I am not going to use it. I philosophically believe in the open source approach so with that in mind I have to practice what I preach.
If you want to use my stuff then go ahead, be my guest. I create all this content to make as big a difference to as many lives as possible. I don’t really care where it ends up as long as it is doing good work.
If you want to incorporate this into your own work then that is fine with me. You don’t need my permission and you don’t need to attribute my work to me if you don’t want to. If you attribute it to me, then that would be an awesome bonus!
The most important thing for me is that if it does make a difference to you, then I want you to share it in some way with as many people as you can.
As far as me using other people’s content is concerned. I try to keep everything original but no doubt I may occasionally recycle an idea from my subconscious that could have been originally someone else’s. If I have done that, then I am sorry. It was not intentional. I am but a human being.
If you are not happy with something on that basis then drop me a line at firstname.lastname@example.org so it can be easily sorted out.
