Imagine someone telling you that they has just opened up a skydiving business and asking you, "would you be interested in learning how to skydive"? If you are afraid of heights you would probably say no.  Should they close the business because skydiving is not for you? Should they decide not to talk to anyone else about the skydiving business because you are afraid of skydiving? Accept ahead of time that what you do and what you have to offer is not for everyone and that’s okay. If they are happy with the product they use, be happy for them. If they are happy with the opportunities they have, be happy for them. Then go on to the next person because they may be the one who really needs the opportunity you have to offer.
