You say this as if you have complete control over your thoughts and the content of your sub conscious mind, which you don’t...

Half the battle of accomplishing anything in life is priming your subconscious mind with the right line of thinking for the task at hand. If you reframe it that way this is fantastic advice.

Edit: I might also add your subconscious mind could very well be considered a separate entity considering it exists out of the full range of your conscious brains influence.

It doesn't make any sense to 'control your own thoughts'. It's weird how people seem to picture their 'real self' as some disparate nonphysical entity in their body pulling levers, in this case even separate from the brain and thoughts

You may wish to look in to Cognitive Behavioural Therapy, as it can achieve what you claim makes no sense.

When people picture a disparate nonphysical entity, it's usually a map-territory effect. Ie. in this case their model of themselves.
