Common misconception is that you can create your reality by just thinking about it but there has never in history occurred an incidence where people succeeded without putting in the work . It works like this , the more you think about something and the more it occupies your subconscious mind your subconscious which is the strongest part almost makes your body accustomed to the idea and you start working towards it and inevitably it happens so ur thoughts make your actions which in turn help you achieve what you want . But prayer can never be substituted by the LOA because prayer is not a communion where you order God to grant you your wishes .
