I remember reading, when quite young, in my teens perhaps, this phrase (or something similar) "When you fully commit to a path, hundreds of tiny things beyond your control start to fall into place to help you achieve it". I'm sure I've mangled a famous quote there, but it always resonated with me, and now a lot of that is reflected in the law of attraction. I don't believe in manifesting but I do think giving your best will rarely take you anywhere else than a better place.
