My Tennis Serve

For a few dayz I was battling with my serve. I normally had first serve %age of around 50, but lately had gone down drastically. I decided to go back to basics. So where would a techie go to learn tennis serve, no not tennis academy...it was youtube & some other videos that helped me recognize my problem.
I was doing everything right except toss. In my quest to put in more top spin esp in my second serve i was tossing the ball over or back of my head due to which i was goofing up badly. So here I put all the basic steps.
( I am not a tennis pro but a lover of the sport, so please add comments & videos for improvements)

1. Position yourself: Right foot at around 45 degrees to the base line, comfortably puts me in a nice position .
2. Focus: Focus focus focus, i do it by bouncing the ball few times...forget about last point, last serve, people watching, cute girl somewhere nearby :) ...forget everything just you and the tennis ball.
3. Pickup a spot: Everytime before serving I look and pick up a spot where i intend the ball should go.
4. TOSS: This is so very important. You need to toss the ball at a convinient position for you to hit. As for me it just above the base line little away from my body. This below video also very clearly shows the starting position of hand before toss and a good toss by Nadal.(dartfish)


5. Reach for the ball: As the ball is going up, start bending the knees and when its at it highest reach for it and hit it as hard as you can.

Below is the video that talks about all the steps in much more detail.
