You need to adjust the pushrod on the clutch master. It's the rod that connects the M/C to the clutch pedal.

Loosen the locknut and adjust the rod counterclockwise to thread more into the clevis. The clevis pin should spin easily with the clutch pedal all the way up.

^^^^^^^^^^^^^^^^^
and that will make my clutch engage sooner????having it engage late like it is, is that bad for the clutch??? cuz my first clutch went bad fast and it really messed up the flywheel and pressure plate. im just not sure if i drove it wrong or is it cuz the pedal is so late??

That should move the engagement point lower. With the engagement point so high, it's likely that the clutch was slipping most of the time. That would cause damage to the flywheel/PP.

Alright, everyone needs to just stop. Adjusting the clutch pedal has been discussed many times. I personally wrote many threads, including detail pictures about the proper procedures on how to adjust the clutch pedal.

You can adjust the master cylinder piston travel at the bottom of the clutch pedal travel. Too much and the engagement is moved towards you. Too little and the clutch won't disengage at all.

This adjustment is made with the master cylinder rod. You can move it in or out. When you launch the car, this adjustment affects how soon the clutch will start engaging when you start taking your foot off the clutch.

It's better to adjust the engagement point too high up than too low because the clutch won't disengage completely.

The person above who said that a high engagement point causes clutch slippage has better be talking about the clutch pedal backstop.

You can adjust how far out the clutch pedal comes out when you take your foot off. Too far and it will give you a longer pedal length. Too short and the clutch will never fully engage.

It's better to adjust the pedal travel to be too far out than too short.

This adjustment is made with the clutch pedal stopper bolt. It affects how much clutch pedal travel you have after the clutch is fully engaged before the clutch pedal hits the stop.

As the clutch disc wears in, these points will change so you will continue to have to adjust.
