Just see what's on your mind most of the time. It might be your daily affairs, your family etc. but there might not be any place for God in your mind. If you do not remember God even once, daily in your life, then no special grace of God is going to be in your life by Him.
It is always good for a person that he does not let God slip out of his mind, anytime in his life. The person who does not forget the God even for a moment, bids fair to realize Him in this very birth.
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."
If a person has the above said assurance of the God, then one should make a resolve that he shall not let God slip out of his mind till he lives on this earth.
Do not let anything else take control of your mind & let God be always on your mind. By doing so, you can have good only in your life by remembering the Lord always. Once that happens, then you shall be able to say, "Wanna God be on my mind - always".
