Hmm, talking about $$$ to be earned most in age of 20 to 30.
Difficult to comment on it. This is the stage for exploring your
life and widening your radar. Many vital connections from you is
definitely empowered your career in every dimension. If it must be
chosen from that list, I will say Banking and Advertising. Why?
Banking supplies your potential RICH connections in future;
Advertising upgrades your communication nature.
Go for it! Cheers
silly banker only earn 2.2 k per month as starting pay for uni
grad
advertising even worse 1.8 - 2k for uni grad.
But later on at the 30 to 40s is the earning region.
Sign on ARMY is good, sign after O level, and let them feed to
support your school fees all the way to uni.
