One thing I didn't anticipate when younger is the extent that other people will prevent your advancement. Whether by being in the way, *isms - a.k.a. refusing to hire you for positions you'd be great at, or very common today... the majority of companies that no longer train or encourage career development. Because you might leave?

Advancement seems to be lot of outmaneuvering these folks.

> very common today... the majority of companies that no longer train or encourage career development.

I don't get this. What is stopping anyone from doing that themselves? Why does someone else have to do it?
