Seriously, it is not all that hard, and for someone with a bit of basic chemistry and math knowledge, most of that reading may be old hat. But on the other hand, it would not be very difficult at all to make yourself or others quite sick, or waste a bunch of money on ingredients and create nasty unvapable gunk, either.
I feel bad piling all of that reading on beginners that ask what seems like a very simple question, but if it were drop-dead easy, there would be no need for this sub-forum. So for Jimmy5878, check those links out, and then let us know how we can help. This is a friendly, helpful place populated by some great people that are eager to share their knowledge and experience. But, IMO, the price of admission for someone starting out from scratch is a bit of homework.
