The saddest thing in life is when one does not permit one's self to dream.
My late father (may God rest his soul) once said, in the most vulgar Cantonese you can imagine, "If you are to pick up a piece of shit to eat, be sure to pick up the biggest piece." (擔屎都要擔最大塊來吃）
I don't understand why this saying left such a strong impression to the young me, but I somehow understand/ interpret it as "Be sure to dream Big, very very BIG." Aim for the Sun, not the stars, what could go wrong? Literally nothing.
If you don't believe that you can overcome your hardships, you may very well be the only one who's limiting yourself. If you fail to imagine that you could live life exactly the way you want, if you fail to visualize it, you will fail to turn your dream into reality when you just can't see it.
When I used to conduct job interviews, one of my favorite question was, "If money and time were not an issue, how would a day of a successful you be like? Not the you who's heading towards success, but the you who have already achieved success." Obviously, there's no right or wrong answer, but this question is simply to understand whether the candidate has a clear picture of what his or her definition of success is. If one has yet to even dream about it, it merely suggests that the candidate does not have a clear idea. Said candidate lacks imagination and ability to dream.
It costs you nothing to dream, and if you can dream it, you can do it.
Have you ever dreamed of success? How thirsty are you for it? If there's a will there's a way.
