The first couple weeks of vaping for me- I used every possible excuse to smoke an analog. I was looking for excuses, and now I see that. After the cancer diagnosis I was looking for ways to make it work. Plain and simple- that's the difference. You either want it, or you don't. Before cancer I didn't, after cancer I did.
I just saw some crappy infomercial the other day for an e-cig, and they kept saying over and over "it tastes and feels just like a real cigarette" and I KNOW that's not true- because even the highest end devices and liquids don't taste and feel "just like a real cigarette". But the advertising leads people to believe that you remove analog, insert e-cig and it's all the same. And it's NOT. People think they're doing it wrong, or that there's something wrong with them, or whatever- and that's not it at all.
But the truth of the matter is that if you truly want it to work, you will find a way. You will learn and experiment and try and try and try until you find something that works for you. And I guess that's not something you can teach someone.
