Being a Bitcoin Evangelist

I first got into Bitcoin during the run up of fall 2013. I work at a small company where I am a salesman and we have about 4 other sales guys in our office. I am generally the highest selling guy or within a small percentage from the top.

I have evangelized about Bitcoin on such a regular basis over here these past 3 years it has made everybody sick. Nobody is interested. Not the least bit. The data, the vision, the potential that I have sold on these guys has all gone in one year and out the other.

I am not trying to 'sell' Bitcoin to these guys but I was thinking, am I bad at evangelizing this or will this group just never get it? Does it take a special type of mind to wrap around the idea of Bitcoin during this stage of its existence?
