To all people out there, please listen to what i am about to say...
Life is too short to be wasted on ignoring the opportunity that pass by.  We spent 20 years making mistakes, 20 years performing activity daily of living, 10 years of making plans, but the opportunity might last for us only for a day.  if the door closed, it might remains closed till the 'opportunity' thinks that we are ready for it.  one door will lead to another.  don't be afraid of knocking the wrong door because if that is the wrong door you will end up facing the right door.  Maybe on the time that you made the decision to knock on the wrong door, you are still not ready for the right doors.  entering the wrong doors are still better that staying at one place spending 20 years making mistakes, 20 years performing ADL, 10 years making plan and end up with no outcome.

So, open your heart, open your mind and open the doors..  :)
