Hi Mei-la Chi,
What is the limit of our time and who can say how much of our time limited ?
ONLY WE CAN DO IT !
So, if you really want to do something, if you really want to succeed than for you there's no limit. Anyone who wants to work will find the way and time and who will not, they will find an excuse.
Well, to those who want to pursue this business "DO it NOW" , sometimes "later" becomes "never" !
