Your talent can be honed by a good guru , but just lagan is not enough. So many students get their doctorates in music. They know about the technicalities of music but are not great singers. To some extent, visibility is also important. You have to give concerts, or else you will be forgotten.
Jealousies are everywhere.
Healthy competition can be good. Jealousies cannot finish a career because real talent does not go unrecognised. Real cut-throat competition comes to the fore when a show to be staged abroad has to be sponsored. There is lot of corruption involved, you need connections in high places. Yes, at times we do go for each others' shows.
