Once you accept that you do have the power to transform any given situation, given your unique talents, skills, and access to resources, you will find that your ability to creatively problem solve is tremendous.
Nobody can take advantage of you if you don't let them. Someone can't take all your time unless you give it. Being nice should make you feel good, not like an unhappy victim of people who abuse your kindness.
To maintain your personal transformation, remember that what you focus on is what you get. Mindfulness means keeping your mind on positive thoughts and actions and pulling it back when it wanders off course.
When you master the art and science of the paradigm shift, you're able to make life as meaningful as you like. You're now able to clear the obstacles on the path to the results you want and need. You can silence the whining, self-pitying monkey mind any time you like.
