Which courses should Bollywood celebs start?

If at all, Bollywood stars had to start own courses, coaching, classes or write self help or 'how to learn skill' book, teach something then who should teach what, according to you?

IMO, Amitabh Bachchan would be perfect to teach language, voice modulation, public speaking, pronunciation, diction. SRK can teach communication skills, personality development and entrepreneurship.

John can teach fitness, diet, how to achieve good physique. 

Rekha can teach bridal make up and dressing.

Sunil Shetty can teach fitness and entrepreneurship.

Akshay can teach martial arts and be a fitness trainer.

What courses, do you think, any star could be better off teaching?

Rani jewellery shop assistant

Jaya jewellery shop owner

Srk stop smoking advisor

Chunky pander actor. Coz he's not been one so far has he.

Anil kapoor zoo keeper

Sonam kapoor... ummm err air hostess 

Why did you choose gynaecologist for Arjun Rampal? I am curious. 

Cariii is killing me with her suggestions....🤣

Course to get by with the bare minimum no matter what 

Jaya is better off training discipline in charge at schools and taking rounds to tame kids at schools or training hostel wardens.
