The word of the day is the Law of Averages. It is the idea that probability will influence all occurrences in the long term.
For example, in a fair toss coin, you have been getting heads for the third time, chances are you will eventually get a tail in one of the next tosses. If you have been losing for the longest time, you are probably going to win the next. In short, one will neither win nor lose all the time in the long run.
If you have been feeling f*cked up for the longest weeks, chances are, you are going to feel awesome one of these days.When it happens, accept it. And if doesn't? Well it is probably a good idea to wait. Oftentimes, it is just a matter of time.
