In addition to what Sunbeam said, I listen to music, especially music that gets you energized... I even have a playlist of songs like Thunderstruck- AC/DC, Back in Black- AC/DC, Welcome to the Jungle- Guns n Roses, Levels- Avicii, etc... I listen to that in the evening before and when I am warming up. It helps me not play the kind of crap unenthusiastic tennis that I played in Jr. Orange Bowl by raising my mental intensity level.
