Anyone can be a trainer?

No, as training like teaching is a profession which requires fashion and flair.While you can develop the flair, passion is something which comes from within and is natural. You might start off training as someone is offering you a hefty,but over a period of time you are bound to loose out on the motivation, which would reflect the absence of passion.First understand whether you are passionate or not and then kickstart.After all money is not everything, satisfaction is more important for a person to enjoy a profession.
