When Told You Are Overqualified...
I don't think there is such a thing as too much experience. There are only companies that don't want to pay you what you are worth. The other side, the consequence is that those companies tend to have a revolving door when it comes to retention of skilled people. This is an ineffective practice due to the effect it has on everyone at any given company, it can only create instability.
I think for most we would prefer not to be in that type of situation in life, because one's status tends too change to frequently, and usually catches one unprepared; for we never know or even have an idea when major changes will affect our well-being is coming.
On the flip side of the coin its the saying Where One Won't, Another Will. There always more than one way to look at everything, just like a coin it has two sides and multiple views. However, you can set your glaze upon whatever point of origin you choose, and if you look at anything or tell yourself something long enough it will become true, even if its core is based on an untruth or right out lie, such as believing in Lack, and here's another saying:
As A Man/Women Thinketh, So He/She Becomes.
