The missing part in the Law of Success
In order to succeed, either any doing towards this success should be completely selfishless or alternatively you should be completely aware of your selfish motives.
Then the universe will support your doing.
As we can hardly do anything out of complete selfishless, we better focus on the path of complete awareness of our selfishness, of our selfish motives. But complete awareness of our selfish motives requires us to be completely honest with ourselves. And this is also something almost impossible, but at least it is easier than being completely selfishless.
So, being, for now, neither completely selfishless nor completely aware of your selfishness, you are left, for now, with the doings that are natural to you, doings that happen, doings that do not necessitate a crucial support of the universe. Be happy with them and meanwhile work hard on your awareness to your selfishness, don't waste time on working on your selfishless despite the solicitations of the ego.
This is the law of success. They hide from you, for some reason, the complete selfishless and awareness stuff. They hid it probably because it makes the whole thing hard and they know they can only sell you, a lazy one, solutions that look easy. Anyway, they know, due to this same laziness, you will most probably never check it seriously and and find out that it doesn't work so they feel safe to promise anything.
