As humans, we can wait for good times and good times come to us but when good times come we may not remember them. But we can remember bad times quite well. Life is easy if we can enjoy it but along the way we complicate it. If we look around us, we will see that many people are suffering more than us. If we look at them and compare them, we can consider our good times compared to them. I think it's more important to set ourselves mentally than to wait for good times to come. Because in our society, there are people who, despite being in a lot of danger, feel very happy and accept anything with a smile.
Bad is twice the impact (of not more) than good.
The problem with comparing to others, is that we all have different experiences. Some things are incomparable, even if they have similar conditions otherwise.
