You’re dealt certain cards in life: sometimes good ones, sometimes bad ones. You use the information you have to make the best decision possible on how you want to play your hand. Sometimes you get lucky and things go well. You make a good hand and it pays off. Other times, you’re not so lucky, you run into a bad string of luck and you appear card dead. And such with life, there is always a decision, and sometimes the right move is to give up, fold and play again another day.
At the end of the day, sometimes you can make all the right moves, but it still doesn’t work out. Because you know, that’s life.
