I use my mantra as a mantra: "I'm Dreaming"

a mantra is a:
a statement or slogan repeated frequently
slogan, motto, maxim, catchphrase, catchword, watchword, byword, buzzword

It is kind of something running into your unconscious. I recommend trying to working on your focus. I have ADD and I was able to say my mantra aloud for an hour one time trying to cement it in. Try it throughout the day while meditating and choose your mantra very carefully.
