1. Know thy weaknesses
2. Seek great coaching
3. Practice practice practice!
This is how I quickly went from a 2.5, to a 3.0, to a 3.5 then a 4.0 and in 2016 after just 7 short years of playing - I became a 4.5 player!
And as I improved my health also improved too!
Tennis is a miracle worker for my body, brain and heart too!
