You and you alone are responsible for your life.
There are people along the way that help, but there is no guarantee that they will stay.
Everything in your life is the result of your decisions. To have the life you want is to take ownership of your decisions. No one else is going to decide strictly based on what is best for you.
Many times in life we make the decision not to make a decision which means we will get a random result.
It is far better to consciously make all decisions. This requires you to be aware of when decisions are being made.
If you watch TV at night, that is a decision, but it is more than just a decision to watch TV. It is a decision about what to do with your time and what not to do with your time. If you took the time to determine all the things you could do with your time at that point and the pros and cons, would you make the same decision?
Become conscious of all the decisions you make in your life. There are literally dozens of them every day.
