Perhaps you are stuck in a old mind-set that keeps sabotaging your growth. Changing a mind-set has to be intentional, deliberate, and calculated. Sometimes because it has been imbedded their for so long, it may take a shovel to dig it from its roots, or possibly a hammer to crush the defeated thoughts to pieces. Whatever the measure you have to take its worth it.
On the other side of the mind-set is another life. Possibly a new career, or a new business venture, or a healthy relationship. Whatever, is on the other side, its time for you to go get it. Start today, and make a list of your defeating mind-set thought, than write actions you plan to take to rid yourself of them.
