There are loads of progressions out there. Some stay in one key others go in and out of other keys.
The best thing to do it to start analysing other peoples progressions. A very popular progression is the I - IV - V progression. This features in many many poplular songs that you will know.
I - IV - V represents the first, the fourth and the fifth chord from any given key.
So to play a progression in C we take the chords of the key of C
C - Dm - Em - F - G - Am - Bdim - C
The I chord is C
The IV is F
The V chord is G
Play these chords and you will have just played hundreds of songs!
