Thanks for the post, Blake.
I have the most trouble with the second and fifth point that you mentioned. It's like everytime I try to hit a ball that I'm not used to, I just freeze up in my mind and the stroke just fails.
That's what holds a lot of good players back, the "feel" part of tennis. Really try to work on it, the better you get at it the more options you'll have in rallies. The feel part of tennis is really underrated in a lot of club level players, atleast the one's i've seen/played against. They usually work on technique, consistency, timing, footwork, etc. All of this is important, but they don't work on anticipating and seeing how players move/hit and how it affects the shot your opponents hit, or try to limit your opponents options, develop certain plays, or work on constructing points. Improving the feel part of tennis is highly beneficial, because you can see the ball coming earlier, you'll have more time to get to the ball, more time to prepare and hit the ball, and also have more options opened up to you. This will make it easier to be consistent and have better timing (theoretically), and you'll achieve what you were looking for in improving your footwork (getting to good position, and getting to balls you couldn't normally get).
Improving the feel part of tennis is harder then improving footwork, consistency, timing, technique, etc for most players. The others are basically learning different sequences/strokes/ where to hit, a lot of repetition, and making them "usable" in matchplay(they by no means are easy, and get harder as you move up the tennis rankings, and the advanced strokes/movement/shots make it harder). But the feel part of tennis is hard in a different way, because it's more a learn by your self thing. There are certain guidelines, like basic ways to tell where your opponent could hit, but overall it's something you have to learn yourself, by experiencing and paying attention and learning what you see. There are also different ways to use anticipation and reading to your advantages.
Federer and Nadal are great examples. Federer usually uses his amazing reading/anticipation abilities to get to the ball as soon as possible to attack. Sometimes he's already in position to hit the ball before the ball lands. Nadal on the otherhand usually uses his amazing reading/anticipation abilities to get to every ball. Although they both can use anticipation for attacking and defending, that's what they're usually known for, and in my opinion the best at.
