If you want to be more successful in any area of your life, there is one single step you MUST take before anything else. Nothing can affect any kind of positive change until and unless this step is taken first.
Recently I came across best written example I've ever seen that emphasizes importance of this crucial concept. I don't know who originally wrote it, but I found it in a great book called 'The PowerMind System'.
It's a poem called, "It's Your Fault":
If you hate your job and you DECIDE to stay there, it's your fault.
If someone offers you a better job, but it requires you to move to another city, it's your fault.
If you DECIDE to save no money during your working lifetime, winding up broke and embarrassed at age 65, dependent on charities for survival, it's your fault.
If you DECIDE not to study or read in your chosen field and find yourself never rising above mere mediocrity, it's your fault.
If you DECIDE to spend more money than you make, running yourself into debt by satisfying one capricious whim after another, it's your fault.
If you DECIDE to waste all your time on meaningless activities, neglecting all important things you could do with your life, it's your fault.
If you DECIDE never to read a self-help book and then suffer dramatically because you are ignorant of success principles, it's your fault.
