Going Pro, What should I tell the boss?

[Piemaster]

Why do you need to lie or hide the truth at all?

When I went pro, I told everyone at work the truth and they were really interested, impressed even. It's not the same as leaving for another company (which always causes a little resentment) because they realise that you are going to do something that (seems at least) really interesting, almost like a dream job. My ex-boss says she still uses me in presentations as an example of somebody who followed their dream (LOL).

Have you any reason to think that they would react in a negative way?
