If you are not satisfied with your life, change is possible. You can change it.
To change it, you must desire change enough; and follow that with a change of how you think and what you do.
You cannot change unless you change.
What does this mean?
That you cannot change unless you change your attitude, your thoughts and your actions.
Change in your life will only follow a change in your thinking, your attitude, your behaviour, and the things you do.
And since you know this, what is holding you from changing?
