Everything and everyone around you is a reflection of who you are. Yes, everything and everyone.
This is not so much a statement about improving your image as it is a statement of embracing your spirit for what it is and what it could potentially become. The things that stand out to you the most are the things that really mean something to you. An area of blight triggers thoughts of blight in your life. The habits of others that annoy you are probably the habits you fear you may be showing to the world subconsciously.
The good news is that if you can see it in others, you can emulate or repress it in yourself. Don’t look at things others do in the form of envy or shame. Look at things as a blueprint of what you can become or overcome, depending on the circumstances.
