The most important thing to understand about life is that no matter who you are or how much money you have, you are never going to be able to get away from the difficult times that come with life. There is no way you can live your life thinking that everything will always be easy and there will be no bumps on the road. This is the main reason you need to be careful not to allow yourself to be overwhelmed by these difficult times.
Understand that happiness requires sadness
Imagine a world that allows you to feel happy 24/7 and all that happens in your life makes you feel good and safe? This sounds nice right? But the truth is that if you are always happy, you are going to end up feeling like happiness has lost its meaning. You should ever feel bad about being unhappy. This point may seem absurd but for a man who is not thirsty, water is useless, you can ask a thirsty man the value of water.
