To add to this, it definitely needs to be deep, as close to the baseline as you can get it.
It doesn't have to be near a sideline, but should be down the line, so as not to open up angles for your opponent.
Hit low, with slice using the continental grip, the same grip used to serve and volley. This is so the ball will stay low, forcing your opponent to hit up, so you can angle it off for a winner.
Now hit a million practice balls.
