You have to go deep inside your head, suspend your doubts and disbeliefs for 10 - 15 minutes, and just for that period of time, do your visualisations and affirmations etc.
The key point is this - if you can go deep, and if you can suspend your doubts and disbeliefs just for that short period of time, then you have a very good chance of success.
By going deep, I mean states like alpha and deep alpha; and maybe even the theta and the delta.
I have one warning for you guys. All your current beliefs, including the apparently negative ones, are there for a reason. In some way, they serve you now, or have served you in the past. Before you decide to root out a belief, even an apparently negative one, you should do some careful reflection about whether this belief actually helps you in any way.
At the very least, acknowledge the following risk - if you rip something out from deep inside your head and insert a new, very different belief into it, you are inviting big changes into your reality. These changes can happen quickly, and you may find difficulty adapting (even if the changes are positive).
Take it from me - all the recent troubles and woes in my life right now are quite obviously caused by my own ...
successful ... LOA experiments.
To put it in simple terms .... Be careful what you wish for, because you might just get it.
