The best thing to do as a simple rule in life would be to "Believe" in yourself and very little in everything and everyone else.
But one should "Suspect" everything that exist around you to have some truth within it.
You have to undo all the programming and undo the imagination of the others which has been projecting on you and has been downloaded into your brain since birth.
Be as a child and use your own imagination and leave the others who are hammered into matter by the survival of nature and its manifestations.
The truth hides within the hidden part of your own creation of your reality.
As remaining on the quest might be about witnessing all the creations from your own imagination as well as of your own past memories, the present of your now, which is in a survival mode and the future of your dreams.
Remember it is the others who are constantly hammering you in to their imagination and their reality also.
Maybe the journey is learn these lessons from your hidden self, which is remorse and your regrets.
But alway try to remember that once you carve into stone the commitment of "Believing" in someone or some idea those beliefs will close your mind to any and all other possibilities.
And in doing this you'll have committed not only your soul, but your hidden spirit as well, which your hidden spirit is like untouched clay of your imagination as you're always "in the now/now-ing" shaping the clay of your spirit into your own reality that you imagined life to be or not to be.
To "Believe" is to end the quest.
To "Suspect" is to begin the quest.
To ask questions is the quest,
To keep an open mind is the journey,
Its best to keep an open mind and use common sense as your guide and stay on the quest here in this world as well as your journey in the next world.
