It sounds like your dilemma is based on 2 factors: Happiness and
Money. The combination of which results in the following 4
situations:
1. Happy doing what you do, and making good money from it.
2. Happy doing what you do, but not making good money.
3. Unhappy doing what you do, but making good money from it.
4. Unhappy doing what you do, and not making good money from
it.
Clearly (4) would be the least desirable situation and (1) would be
the most desirable situation. You sound resigned to the fact that
you are only faced with (2) and (3).
What you have to realize is that regardless of your choice of
disciplines, these 4 situations always exist. Granted, the
probability distribution of these 4 are not equal for all
disciplines which is why people concede that it is easier to
succeed in certain disciplines than others.
You should also realize despite the higher probability of success
in some careers more than others, the probability of failure still
exist. Which is why you should never back the guy at a casino who
tells you "If you did Accountancy/Law/etc you're sure to make lots
of money and live happily ever after!" or "If you did Liberal
Arts/etc, you're sure to be poor and unhappy!"
The only sure things in life are Death and Taxes. Anything else is
subject to the laws of probability. What you can do is manipulate
the odds through choices, effort and luck. Work smart in addition
to working hard!
I do suggest that whatever you decide to do, make sure that you
always have options. Even at this point, it's hard for anyone to
know for certain what they'll be doing a year from now, much less 5
or 10 years from now.
Liberal Arts in itself is not a career. It is a discipline that
prepares you for a variety of career paths. It is not inferior to
any other discipline. Neither is Accountancy/Law/etc superior to
any other. The right combination of all disciplines results in the
synergy that is success. Similarly, Singapore was not built on the
backs of accountants, lawyers, doctors or engineers alone.
Decide what it is you can see yourself doing 10 years from now,
then figure out what you need to do from now right up to that point
to be able to get there successfully.
Life is not a routine; it is an experience. To take a quote from an
outstanding movie from Peter Weir (Dead Poet's Society) - "Seize
the day. Make your lives extraordinary."
Be the best you can be in whatever you do, benefit from the wisdom
of those who have gone before you... And as Mark Twain so aptly put
it, "Above all else, to thy own self be true."
Good luck... you have your whole life ahead of you!
