My clutch until I drove it a while, then clutch pedal tight and clutch slipping

What is your question?

clutch worked well, proper play in pedal but changed as I drove it (first time driving it) and adjustment was out, had to baby it so clutch would not slip, I stopped pressing pedal all the way down as it started to stick down. had to pull it up and baby-clutch it to shift.

What makes this problem better or worse?

got worse as it heated up.

How long has your 2004 Chevrolet Aveo had this problem?

owned the car 1 day.
