After reading others response, to me, personally, the most undervalued asset are my parents.
I do know this is not what the author wanted but after reading others response, my two cents on this aspect
As far as financial asset is concerned, the most under rated (i would say not undervalued) are our FIXED DEPOSITS, post office mis, kissan vikas patra ( not sure if it still exists)
I agree. Do not really find them to be undervalued or underrated. If no awareness, the first thing major chunk of the populations park their money is into Bank.
However, you may have your own reasons for you to believe this. After all, what we value and what we do not in the financial world comes only after experiences.
@raoawesome personally, I super agree with you. If learned and applied well, what an asset these both could turn out to be in the longer run. After all, the wealth that stays with you after you earn it is directly/indirectly a result of your management and emotions towards it.
