What you focus on grows. If you have an idea of something that you want to do or create your mind comes up with all different sorts of ways to make it happen. When we are worried about something bad constantly thinking about it just makes us feel worst. What you concentrate on can make or break you. So why not give into the positive, feel good things that will bring you joy?
Appreciating where you are and what you have will lead to a more fulfilling life. And if you want more from life work to achieve those goals while enjoying what you have.
Anything is possible if and when you put your mind to it.
