do you draw
I do, yeah.  I have a degree in Studio Art, believe it or not.  I draw on all kinds of materials:  cardboard, plastic, canvas, board, wood.
you must be pretty good
I think drawing and painting are great modes of stress relief.  Painting stretches back to pre-historic humanity, and it's something shared by all cultures around the world.
yes i wish i could draw better
I don't believe it's about how "good" you are.  If it's something you enjoy, then you should absolutely go for it.  You can use all kinds of things... chalk, pastels, markers, wax pencils, and you can even use a tablet to draw digitally.
i'm not to good at it 
What about just temporary drawings?  You could practice using a black or white board.  Easy to erase!  That way, you don't have to spend too much on supplies.
i guess i could try
Just start sketching!  Quick little hand drawings that get the general idea of what it is you're drawing.  It's a great way to start.
