So just have faith & belief that you are a Soul, and that you live in this physical body. Your Soul is part & parcel of God, the light of the Lord. God, Your Savior, is guiding you into all the truth through your Soul. You are a child of the God, born of the Spirit of God. Having such thoughts you shall always delve in God.
As per Bhagwat Gita, think yourself to be that Soul which is beyond this body, which is unthinkable, imperishable, ineffable, eternal, all pervading, immobile, un-manifest & immutable. In fact your nature is also that only which is also called Brahmn. Also see the same Soul present in other beings as God is seated in everyone's heart. When you shall see God present in all the people around you then you shall always have God on your mind.
"aham atma gudakesha
aham adis cha madhyam cha
bhutanam anta eva cha" (Bhagwat Gita: Chapter Ten verse 20)
"Sri Krishna said: I am the Super Soul, O Arjuna, seated in the hearts of all living entities. I am the beginning, the middle and the end of all beings."
Other than this just have devotion in God as through devotion towards God, He shall always be on your mind. Lord Krishna says in the Bhagwat Gita: Chapter Eight verse 14
yo mam smarati nityasah
tasyaham sulabhah partha
nitya-yuktasya yoginah" (Bhagwat Gita: Chapter Eight verse 14)
"Lord Sri Krishna says: Whosoever, always & constantly remembers Me with undivided mind; by that person, I am easy to obtain, O Arjuna, because of his constant engagement in the devotional service to Me."
