Is it best to be a dreamer or is it best to be a doer? Actually, it is helpful to be both.
In all great creations, the idealistic exists with the pragmatic in elegant proportions. A dream is of little value unless you put action into it, and action won't get you very far unless there is meaningful purpose behind it.
Allow yourself to dream grand, magnificent dreams that express the deepest essence of who you are. Then let those dreams pull you steadily through the practical, nuts-and-bolts work of making them real.
Work through each day with diligence and persistence, doing what there is to be done. And as you do, stay close to the dreamer that always lives within you.
As a dreamer, you can envision a world and a life with no limits. As a doer, you can focus on something that has never existed before and make it real.
Let your most treasured dreams focus your actions and let your actions express your dreams. Be both a dreamer and a doer, and dive deeply into the multifaceted treasure that is your life.
