This or that?

You cannot fly by thinking of falling on the ground.

You cannot swim by thinking of drowning.

You cannot save money by thinking about your expenses.

You cannot lose weight by thinking of eating high calorie foods.

You cannot create good health by thinking of getting sick.

You cannot be a topper in school by thinking of getting fail.

In the same way, you can never create a happy life by consistently thinking of things that are making you feel bad.  If you want to create a happy life, your thoughts need to be shifted from things that make you feel bad to the things that make you consistently feel good. You cannot make your life positive, by thinking all negatives.

So it is in your hands to make your life either happy or sad.
