Manifesting is all about choosing your experience of life.
Feeling content and happy for no apparent reason attracts the external circumstances to match those feelings.
Just like magnets move towards each other, what matches your vibration moves towards you and you are guided towards what matches your vibration.
So feeling happy attracts more happiness to you along with all the things that cause that emotion within you.
Feeling loved attracts love to you.
Feeling wealthy attracts wealth to you.
Feeling successful attracts your personal definition of success to you.
But if you have doubt over your worthiness or deserving of those things then you split your energy and your magnets lose their charge, resulting in your manifestations taking longer to appear – if they appear at all.
