Responsibility is a sign of maturity, and taking responsibility for your actions or inaction is the first essential step towards any sort of growth. As long as we blame our lives on circumstance beyond our control, we are living the life that someone else has designed for us. Once you accept that your life–and everything else in the universe–is a result of cause and effect, you can start initiating the causes that trigger the proper effects.
If you continue to blame other people, other conditions, the alignment of the stars on your problems, you are not only denying yourself the ability to improve your own circumstances, you’re also denying the basic physical laws of cause and effect.
Remember: change, growth, healing, success. All these things are easier if you have the universe on your side instead of working against you.
