i must be stupid!?

As you know, I've always been wondering about whether I am smart or not.
If I was smart, I would not turn down the one who knows me and treats me nice;
if I was smart, I would know what to do instead of trapping myself...

They say life is about journey; they say you should follow your heart; they say love is inevitible... How to do without regret? Should we listen to what others say?
Nevertheless, one only experiences him/herself through one's entire life...
