Final addition

Working as tour leader for few years while young is okay and highly recommended (if you are less good in academy). But once you reached 25yrs old and above, it will be hard to change job other than hopping over to other travel agency.
I once heard a senior who was reaching 30, has been working in this line for 12years, making averagely RM36k-40kp.a. he said, its hard to find other job. he has traveled until got bored. Losing the passion in travelling at his age bcoz too many places he has visited. Asia countries, no doubt about it. Europe? Few times, Spain, USA, South Africa, Australia, Portugal, Italy, India... several times. He said, where else can hire me at RM3000-3500 per month (basic 2k ++)
but tour guide is different. They are building different type of pipeline while working. Some can get alot of extra incomes like those served foreigners are convinced and fall in love in Malaysia, would like to apply MM2H, they usually will appoint tour guide to refer them seller. and done deal entitlement usually will be extra RM20-30k... (wow!

) and while they are running around, they build rapport and relationships all around too. In short, their future is much secured.
