How do i stop procrastinating?

help! i am the worlds worst procrastinator. i save everything until the night before it's due, and i end up with tons of stress and not enough sleep. i am a perfectionist on top of that, so even when i save everything until the last minute, i still spend so much time making it perfect. maybe i just work better under pressure but i dont want it to come down to that all the time. how do i motivate myself and just get things done?
