A general thought may come to you that how difficult people are around you and this world needs lot of change to make it a better place. These kind of thoughts will only create a bad experience for yourself. There is nothing perfect in this world.
Definitely everyone must contribute to make this place a better world but that doesn't mean it is someone's fault. You are a part of this world and you are creating the world. When you start realizing that you are part of this whole creation, your own way of handling things around you will change.
You will take utmost care in dealing with everything around you. You will stop complaining about things around you. You every action will be towards making this world comfortable for others. This whole change will give you an immense satisfaction.
You will see yourself as a new person once you feel that you are the world.
Cheers,
