The way to take control of the mind is to first become calm, put a little distance between yourself and the mind. Christna says that in the gita. No matter how good one's circumstances are, it can be transformed into a hell by the mind. I think it's milton, the poet who wrote in paradise lost. The mind alone is your worst enemy and is your best friend. Will be difficult, but worth while. Overtime, it changes.
