Hi, it´s me again

I´m reading "Your Best Life Now" by Joel Osteen (by the way, I strong recommend it) and I´ve found many new phrases for me, could you help me to understand them?

Here they are:

* Don´t get mad, get even

* Out of the blue

* Having a chip on my shoulders

Also I read on TV: sweepstakes; what does this mean?

Thanks all of you for your help, I really appreciate

"Don't get mad, get even"

Don't get mad, just take revenge.

"Out of the blue"

It happened without reason. It came from no where. Out of the blue I think is related to "It fell from the sky".

"Having a chip on my shoulders"

Feeling sorry for myself.

"Sweepstakes"

A lottery in which the participants' contributions form a fund that is awarded as a prize to one or several winners

If you're referring to "un favor" I'd be better to say "te debo uno"

To ellaborate, "Don't get mad, get even" implies it's a better use of your time and energy to seek revenge because time and energy spent being angry only hurts yourself.
"Having a chip on your shoulder", to me, means to have a bad attitude and be ready to fight or argue with little provocation.
