Invest on Your Health
My sister is a singer. She used to regularly work with our church music ministry during services, festivals and even crusades. She started at a young age and through out time, she learned a lot, not only in her spiritual life but also in her singing and music skills.
There was one time though that she had problems with her throat. She experienced that due to fatigue and stress. She looked for a good doctor who advised her to take a total vocal rest for a few weeks. Good thing she had it checked as the damaged could only have gotten worse if she delayed her consultation.
Seeing a doctor as soon as possible can really be critical especially to a singer. Though highly unnecessary, there are just times that incidents like these happen, especially when a singer does not recognize that he or she is already stressed. Before seeing a doctor, it can be a good practice to read reviews of skilled nursing facilities in case you would have to be admitted (worse case scenario) to make sure that you are really taken cared properly.
Health is one of biggest things a singer must invest at. A healthy body ensures a good performance and plays a big role for a singer to give a top quality sound.
