Normal for shifting to be "sticky" at times on T5?

[Brant]

I've never really understood that "self adjusting" thing.
I've lifted up on the clutch pedal with my foot, my hand, and every time I feel like I'm going to snap the pedal off.
I've never heard any clicking.....

I rarely have to put the pedal down to the floor to shift...but when she wont go into gear, no amount of clutch helps that

What would some signs be that my clutch cable is stretched out...do they make one that, essentially, won't wear out?
