You cannot deliberately be happy because you wanted to be happy, as being happy is just the outcome of your acts.
Your acts solely brings (or in other words is responsible for your) happiness in this world. Your act of giving, care, thought, time, understanding sets your actions and which in turn is set to bring in abundance and boundless love, which can neither be broken nor diminished by any outside forces as such others acts.
A happiness that is not bound to any factor except your actions led by your thoughts.
So one being down, broken or sad because of unfortunate events (fate as believed by some), financial crisis, family issues is in no way connected to you being happy. You achieve happiness only be acting on your beliefs.
Go Ahead and Do It, Happiness Surely Follows!
