Crappy first drafts

In class the other day, we talked about writing and the time that it takes to write correctly.  Many of us, including myself, expressed that a first draft is hardly ever left to rest, and commonly is the last draft that is written.  I felt that the reason that I did not write more than one draft was because I was lazy.  Thinking about it a little more since then, I feel that it is a combination of laziness that has become a pattern because I am afraid of my first draft.  So as a practice today for my homework, I wrote a crappy first draft, and just let my idea flow.  Having the freedom to SUCK in my writing is now giving the the confidence to be able to allow the idea grow in my head as I let that draft sit.  While I do not know how my final draft will improve from just letting the draft sit for a few hours, the level of stress that I normally have concerning homework has diminished considerably.  Three days in and I'm feeling better and less stressed about writing.
