I'm a great player, a potential top 50 in the nation my coach says. I just need some advice, since my coach doesn't tell me how many hours to practice, he just says what I should do with my practice. I know practice is accomplishing a new skill, or getting something perfected, and so on. But what I really want to know is how many hours I should be practicing? I'm like really obsessed with my hours of playing time, even though I learn something every time I go on the court. So here's what I practice: 5-7 days a week, sometimes 4 but mostly 5-7 PLUS the extra fitness. And each time I practice I practice for 2-4 hours. I practice an average of 15 hours a week to be honest. How many more hours should I practice to kick it up a knotch? Because I'm in la-la land stressing myself out over this kind of stuff.
