How long the lives of human being are?... If we don't even know whether we would have tomorrow or not, why do we care the consequence? However it's really difficult to think this way.
We face various situations and make decisions daily. What to eat, what to do, where to go, when to meet, who to spend time with... some people cares, while the others don't... some people care these, while the others care the others... it's normal that people put priorities on all the decisions... and then go for the important ones. As long as that's what people decide, we should respect it.
We make decisions and review them later, without regret. I still believe that "Choose what you love, and love what you chose." Based on my current knowledge, information, and feeling, I might struggle and then make a decision. If my heart tell me that it's the best choice I want to chose and the best decision I want to make at this moment, even in the future the time go back to the moment, I should still make the same choice and decision, as long as I listen to my heart and try my best at this moment.
Go for decisions... and then smile...
