Hi AndriDem!
It is more like a dog, you attend to whatever crosses your nose. <smiles>
I have 5 dogs.
Anyway, it is all conditioning. Take a good mantra, like 'I AM wealthy, healthy and free'. 'I AM focused joy and peace'.
Not many, kept simple; however write them out a hundred times and repeat out-loud hundreds more (even keep tick marks on a piece of paper to keep track of your counts). You need at least one but two or three is best.
This is 'conditioning'. Keep it light, make a game of it and just keep at it. Ignore failure and distractions.
Thought or thinking is not controlled, only your 'attention' can be.
So once conditioned, you simply 'switch to one of the mantras' as your sub-vocalization choice and do whatever exercise or PhotoReading you are doing.
Even replaying a scene from a beautiful 'day-dream' can be useful.
