Recently I got coaching from Joe Dispenza .
He said in order to change your personal reality, you must change your personality .
It really makes sense, if you want to be a rich person, you must adopt the personality of a rich person, if you want to be a healthy person, adopt the personality of a healthy person and so on.
Think about it like this, do everything the manifested version of yourself would.
Write down everything the version of you would do, act, say when they have everything they wanted and honestly start embodying that.
The 3D world might shoot some tests your way but the best way to overcome them is to really not care.
If you care too much what people think of you, care too much about certain situations then I am sorry the own you in a way and manifestation gets harder this way.
Hope this little tip can help.
