Sometimes you feel that the world is moving ahead, you are at the same place. I have experienced this several times, but the fact is its all is in your thought process. There will be a lot of differences between you and the people who are closest to you. The difference is what makes this world what it is. If everything was the same, then there might not be any fun.
As a human, we need to experience the adversities, which as an individual it build our perspectives. It is what makes tougher things look simpler for you. Because when you experience the tougher things, then it is not tough anymore when you come across it again.
