maintain subconsciousness

the subconscious is a funny thing. something embedded in it can be thought about constantly without the person even knowing it; for that something is existing in the mind, but not immediately available to consciousness. take for instance, when you can't remember someone's name. 4 hours later, as you place a spoonful of baskin-robbins cookie dough ice cream in your mouth, you blurt out: "jake! his name was jake!" how did that come about? for you weren't consciously pondering what his name might have been for those previous 4 hours. or how about that person kris that you are crazy about. next thing you know while you've never said more than 20 words to each other, you think you know kris, you two could be best friends...all b/c kris' actions, previous conversations, and observations, have been actively running wild in your subconscious...
recently a chapel message got me to thinking about this. there has always been that question...what should i do in life? a teacher? a missionary? a missionary teacher? perhaps a marine biologist? but maybe, just maybe, its not so much what i do...but how i think...
if my powerful subconscious was constantly fixated with the gospel of Jesus Christ, then does it really matter what i do? for no matter what God has for me to do in life...my career, lifestyle, daily activities, they would overflow abundantly with the gospel of Jesus Christ...thus leading to His glory being manifested and His will accomplished.
so this leads me to think instead of putting so much thought and focus on what i should do or what does God have for me to do...maybe i ought to focus more and place the effort on how/what im thinking. what is being embedded in my subconscious? what is actively running wild? my prayer, my hope, my ceaseless goal: the gospel of Jesus Christ.
