How to start LOA

Hi guys, I am not all new to shifting, but I have yet tried just some of the methods, like raven. I feel like counting methods are not for me. I tried visualisation methods, and they feel closer. Now I want to add LOA, because lots of you guys claim, that it is very effective. I tried searching, where to start, and honestly, I fing basicaly nothing. I know I should say some affirmations, but that is all. Any tips on how to do LOA? Thank you
