I think if you have a good trainer, you should really talk to them seriously about taking your game to the next level. They are the ones that will help you get their, and are probably in the best position to give you the most honest answer, whether it's the answer you want or not. If you are 100% commited to getting to the next level, then I think it's irrelevant what anyone on here says, or even your trainer! If you can work hard enough, ANYTHING is possible.

Same with the person who posted just above. It is NEVER to late to start boxing. You can start boxing at age 40 and still have another 20 years of fun with it!!! To start boxing at 40 and become a pro? you'd be dreaming,,, but it's never to late to start learning a great sport and keeping yourself fit in the process.... As long as your realistic in your goals, IT'S NEVER TO OLD TO DO ANYTHING!!

Back to the original poster, you should also talk to a doctor and a good physio about your shoulder. Maybe their is a problem their and a good physio might tell you if you continue to box you may fk your shoulder up for life. Now that makes your decision a little easier...

I think anyone on here may be able to suggest things, or give you motivation either way, but when it comes to a decision, that's all up to you.... only you know what you want and probably know whats best for you at the same time... And in a much better position to judge your next move than anyone on here...

Good luck with whatever you do and everyone on here will always be happy to help you along the way...
