I could not sleep and was widely awake at 2:00am. My brain was running actively and as I was reflecting my past and present life, I just realized that life is like scientific experiment vice versa.
We prepared hypothesis but yet to know the outcome unless until we made the experiment which what we called try and error.
In science, the outcome may be either hypothesis is correct or incorrect that there is a need for alternative hypothesis. In life, the outcome is either being upset or happy.
