>You only control your own thoughts, choices, and actions.
This is a tenant of Stoicism, at maximum this is under your control according to that belief, but if you have this dependency on attachment, even that you can't control, then you control nothing and you are controlled by that prison, constrained by fear and limiting beliefs.
Everything is mind, you can control your thoughts, actions, choices, and interpretations and beliefs as well as your perspective. There is literally nothing else, that is your reality. So you can control your reality. And the first step is outlined here
Now take it even further, ask for what you want, that's manifestation. It takes effort but we are in no time on history better able to get exactly what you want through effort. Given everything above, nothing is impossible if you let go of your attachments.
If you need nothing, abundance you will have in everything. (Sounds like a Yoda quote)
