what is enough ??

i guess every time i log in to this blog and started to write is always the time where i'm sad and unhappy ..
surely something happened and gave me the feelings to write ...
yes .. i'm not in mood again ..
after exam i should be in perfect mood because its so relaxing and stress free ..
but well .. i'm not .. not even a little ...
reading the past few post of mine .. i actually wrote about accomplishment in life ..
i talked about the success of my college life .. yeap .. i'm proud of it ..
but only one accomplishment is not enough ..
i need a balance in life ..
seriously need it ..
few years ago .. i thought i had found someone who i love ... but its not .. struggle goes on till this year ..
and things started to change ..
i found someone who give me hope in life .. but somehow .. i'm not that sure about it ... i doubt myself again ..
this type not doubt about feeling but doubt on my capability in sustaining it .. i guess the problem came back to being not enough ... while i thought i'm actually giving my best .. it turn out to be no ... he cant really feel it ..
im sad enough to know that ... my very best was nothing .. was not enough again ..
so what is enough ?? i seriously got no idea ..
