notes on what i've learnt:

take everything with a pinch of salt. sweet words are but words. actions mean so much more.

never waste your time/money/effort on things/ppl that wont reciprocate nor appreciate your effort. (not saying that you do everything with an expectation of a return)
just saying that.. sometimes, its better to care for something/someone that appreciates your caring and cares for you just as much. dont waste your time feeling sad/hurt when someone doesnt even care that you've been hurt by their actions. move on. smile. because such people shouldnt mean anything to you when there are so many others out there who loves you and appreciates you so much more.
