Affirmations are great but if they are not aligned with an elevated emotion and a high vibrational match it will take a long time to get where you want to get.
It’s a way of meditating. Thoughts will come up because it’s the nature of the mind, but let them pass, don’t get attached to them.
Another point is that when you’re aiming high, it’s not enough to casually choose something. You must choose with your whole being. So arrive into that high alignment with this desire that’s to hold and feel it in your body.
Your body then becomes the vortex to your future, for what is serving or taking away from the growth towards this manifestation.
