Don't be 'sniffy' about selling

Logic alone rarely gets full 'buy-in' to an idea; the idea will need selling. Don't be adverse to that idea. Ok, you trained for years and you have a whole stack of vocational qualifications plus an MBA and you are not sure about doing something which apparently anyone can just 'walk in off the street' and start doing. Here's why you need to start getting good at selling:

-you'll increase the % of your ideas which are accepted in meetings
-you'll be able to handle resistance to your desired salary increase
-one day you'll be running your own team or division or business and you'll have a quota to hit. The sooner you know how to do that, the better
-selling is exhilerating
-simply because it's not such a highly regulated industry doesn't mean it's easy to be good at it
-it's fantastic being paid for performance
