If you want to become good, play often, or play effective drills, or get a good coach.
If you want to become pro, you have to do all of these things.
Eat, sleep, school, TT. Make sure you have a coach you can trust in serving you a highly effective training program. Train whenever, wherever, and get a sparring partner you can rely on.
Maximize your results by applying laser focus to your training. Select areas to train on together with your coach. Film yourself, analyze, get critical. Build your strong points, cover your weaknesses.
But above all else, your heart needs to be in it. There will be bad days, there will be crap weeks, tournaments you wish you hadn't played. Take the lessons from those with you, and let the bad stuff slide off, slowly if you need to, but fast if you can.
Enjoy the sh*t out of the process, fall in love with not just the sport but the whole package of professional athletics.
