You can you use quotes, mantras and sayings to focus.
The mantras can be very simple.
You take a deep breath and repeat them on your breath out.
You can vocalise it or say it to yourself.
Here are some great mantras for you :
-I am grateful for everything;
-I am love;
And many more.
I wrote a whole book on the subject.
It is called: "Say it". And it is available on this website for downloads.
Meditations are tremendous, and they can be supercharged.
