According to you, what best Job, business or profession or farm?why?

Everything is best, only if you feel comfortable in it.

I agree with Mr. Vinod Jetley

And as per my own experience I found my self in the Airlines sales field

in the Fares, ticketing and reservation duties you are daily raise your skills and learn new thing

really it was very exciting

Depending on what you are looking for, just try to get the best out of the job
