You attract what you are, not what you want. So, the process of using the Law of Attraction is to become what you want so your vibration matches it.
If you want abundance, feel abundant. If you want love, love yourself first. Those things are already inside of you, let them come out into the open.
Most times things don't manifest instantly because we do have certain stages we need to go through, or experiences we need to have to prepare us for what we want.
Trust the process!
It's absolutely true ...
There is a truth deep down inside of you that has been waiting for you to discover it, and that Truth is this: you deserve all good things life has to offer.
"What you think you create. What you feel, you attact. What you imagine, you become."
