Hey @wongshiying.. A very apt heading for the post... Everyone must chase their dreams until they get materialized. I believe in the philosophy of relentless trials and someday you would achieve your goal.

I would like to call our a verse from a hindu scripture called "Bhagvad Gita" which says and I quote "Karmanye Vadhikaraste MA Phaleshu Kadachana" which translates into English as "To work you have the right, but not to the fruits thereof".
So, it call out loud that you keep doing your duty and just don't concentrate on the results, as results will come some day but you should also enjoy the journey to get there. Peace ✌️✌️
