Never Dwell on Negative circumstances to the point they make you worry and never use them as as a Motivation for Suceess, the more you Dwell on them the more power you Give them to find Expression in your Life, your Mind is Actually the Bakery of the Happenings in Your life!!!. ‘As a Man thinketh so Shall He be’

Instead Think Positively and visualize your self in that Positive Opposite. If you want to be Rich don’t Even dwell on the Thoughts that ‘i don’t ever want to be poor’ instead picture and keep staying to your self that you are rich or that you are Going to increase in Wealth,this same principle apply to your health and other circumstances.
In fact believe only what the Word of God says about you and about any situation.

Finally, brethren, whatsoever things are true, whatsoever things are honorable, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things( these things alone)

Phil 4:8 (ASV)
