Finding opportunities in obstacles is a wonderful strategy to deal with the problems.
Think about a recent, solved obstacle.
Did it give you new knowledge or skills? Was there an opportunity to change something? At first glance it is hard to find something good. You must force yourself to find at least one small positive thing.
Think about a long-term obstacle.
If you face a problem for a long time, think about its roots. If it is connected to work - maybe it’s time to changes, to look for new opportunities. If the problem is relations - maybe we can improve them, maybe we can change something in our behavior and thanks to it be a better person?
