You keep hearing about, and seeing, the phrase Self Development. (Also, Personal Development, Self Growth, Personal Growth...) But what does it really mean to you? For example:

* Do you look on it as an airy fairy subject?
* Is it just hype or is it tangible at all?
* How important do you think it is?
* Who is it most relevant to?
* Why do people invest in it?

I'd love to hear your thoughts on all this - feel free to be as critical as you wish.
