Would like to know what little things you have picked up over the years that the rookies might find helpful as they start out. Things that might help you on your serves, fh, bh, slices that most people don't know about. For example, off the top of my head I can think of two things I've picked up 1) On every hit I make sure to take an exhale grunt, makes sure I'm relaxed and not holding my breath as the point goes on. Most people prob. do this but for my first half year into tennis was holding my breath on everyshot lol. 2) Was having an awful time on second serves, noticed I was hitting the ball to flat. So now I get my grip but put my pinkie finger under the butt of the cap, this assures I don't hit a flat ball and thus gives me a nice breaking kick or slice.
