Ballet is hard work but it should still be fun and rewarding. If it isn’t fun anymore it may not be for you. I am not talking about it not being fun one day but fun the next but if overall you find it isn’t for you, it may be time to stop or take a break. You may find that stopping is less fun than going or you may feel like a great burden has been lifted off your shoulders. If you have no joy in class than perhaps it is time to look for another activity or dial back to more recreational ballet training. You are the only one who knows how you feel about it and it will take some serious thought as to how to proceed. Try to imagine what your life would be like without ballet classes. If someone told you that you could never take a ballet class again. That can help a lot in informing your decision. If you aren’t sure, perhaps a break may be helpful in deciding.
