There is no past or future. There is only right now. So as you are wondering if your crappy thoughts from yesterday are ruining your manifestation, you are simply activating that crappy vibe again for completely no reason! The universe has no recollection of what happened last week or even an hour ago.. There's no record taking..  There's just an incredible universe reflecting to you what your dominant vibration is on every topic. So why spend time signalling worry that you're ruining your manifestations each time you experience contrast? So many people waste the magical moment of now by dropping into the past! You HAVE TO understand that there is NO past. It's gone unless you vibrate those feelings again. It literally ceases to exist unless you reactivate it.

Remember today that you have the freedom to signal absolutely whatever you want. So what do you want? Just signal it! I am! Be it. Be the person who IS THAT which you desire to be today.
Contrast is thrown your way as an indicator that you have some stuck energy. How lucky we are to be reminded.. so we have the chance to correct our thinking prior to full manifestation. Every moment is a perfect opportunity to remember who we are,  awaken, realise what our ego is holding onto, and release it fast.
