I always have been thinking about this theory that I realized from my life experience. We are facing problems all the time from anywhere either in a house or a company or in an application or in a country. These problems have improved our experience for the better. For instance having a problem mekes you think more and deeply and Figuring out how to solve the problem gives you the ability to be more knowledgeable about it. It also gives you ideas to develop this thing so it works better in the future.
Also if you have a life problem it improves to you who’s gonna help you with this situation and who’s going to go away and leave you with out helping. Also if you have a problem with someone and that was not your fault it’s going to show you how his real personality is. And sometimes if you have a relationship problem it shows you how much you want to solve the problem without losing each other. And it shows you how it will be if that happen which gives you new feeling and refresh your relationship.
