Look out for yourself. Stand up for yourself. Because nobody else is gonna do it for you. If you are unhappy, create your own happiness. Stop waiting on others to provide it. If you want something, go out and get it.
You can’t control others and you can’t control your circumstances but you can control how you experience it and how you deal with it. So let go of your expectations, stop relying on temporary people and live your life the way you want to live it.
