Bearing and Course, differences?

Hey guys,
I am a presolo guy, about 11 hours now and getting close to solo.
While studying tonight I couldn\'t really figure out the difference
between magnetic/true course and magnetic/true bearing.

So as far as I understand it, bearing is a referenced heading to
somewhere you want to go, for example: I am flying on heading of 060
heading and to and the VOR is on a 090 bearing (Heading of 090
required to fly direct)

Course is an intended flight line, so if I plan to fly from a to b
(with a heading of 090 to b) My course throughout the flight would
be 090, even if I am 30 miles off course, the course would be 090
while the bearing would change, correct?

Can somebody give me easy examples to understand? My next flight
lesson is scheduled for next week...

Thanks guys!
