Performing seems to be an ultimate goal for many students and it is looked at as the "ending" you must reach in the world of belly dancing! Let's say this first: learning belly dancing does NOT have to lead to performance. You can learn to dance for the love of dance and enjoy it.
Many professional performers would die to get their dancing passion back again. Performing could kill this passion because the focus is more on perfection, costumes, makeup, memorization ...etc rather than the emotional aspect of the dance which is what get us all started. Don't forget to LOVE performing if you want to perform.
