Faith, Assurances and the Mind

I have been pondering faith.  If it has to with the mind and how we choose to view things.  If I trust in God that things will work out and that He is watching over me aren’t I constructing in my mind a positive faith view of the matter?  If I go negative or if others tell me that I am wrong and I believe them, aren’t I letting go of the trust that I once had?  I ask and wait.  On top of all that I choose to have charity.  There’s something about helping others that pleases God.  I also become more receptive to inspiration.  I receive assurances as well that God is there and watching over me.  I am under grace.  I really like Alma 58:11.
