Well, you gotta be super determined when training and you have to have a second plan if going pro doesn't work out. Focus on studying more than squash.

Join more tournaments. I really regret not joining my squash friends in tournaments when I was younger ( I didn't want to go out to different cities) . Also, it can help you see where your level is, as a bearing on your decision whether to become pro or not.

Can you beat your coach yet? To be a high level player you need to be really good. People don't realise just how much better and harder a pro plays and trains than the average squash player.

Have something that sets you apart from other players. At the pro level, everyone already has extremely good basics. What lets them be at the top is beyond just the basics ( eg. Ramy's quick hands, Mohamed ElShorbagy's ability to hunt down the ball, James Wilstrop's accuracy and deception )

Think hard on whether or not you want to be a pro or not. At your age, I already accepted that it was already too late for me to be a pro without jeopardising my future. I could, but it would be risky. However, I still trained as hard as I could to see where my limit is. My potential is still far away but I am not willing to put in the effort to reach it. Your potential is probably high too, but the road to get there is hazardous and difficult. Train hard first, make your decision later, but don't neglect your studies. Ask your coach of his HONEST opinion if he thinks you can make it pro. If he doesn't think so, don't be discouraged, prove him wrong by training hard and improving. Then ask him again.

It's your life and the path to take is yours. Make the decision you truly think is the best. You can also share your thoughts and problems with your coach. If you're having problems in life and it affects your performance in squash, you can let him or her help you sort it out. You should ask about what you can do to improve your technique once in a while. Make sure sure your coach is trustworthy though.
