How do you stop thinking negative thoughts?
Think about something else...
How do you see the positive side of life?
Think about something else...
How do you maintain your good mood despite life's circumstances?
Think about something else...
See, life is tough, bad things will happen and you will find yourself in situations you don't want to be in.
You can't control what happens to you, but you can control how much you think about it.
Focus just enough to figure out what to do. Do it.
And then think about something else...
Don't re-live it over and over again.
Don't get stuck in the past.
Don't make yourself unhappy by recycling all those negative thoughts.
Think about something else...
Think about something good.
Think about something positive.
And remind yourself that - in the end - the good outweighs the bad.
And this too shall pass...
