Paradox: Knowing What You Want Clearly & Detaching from Outcome

There seems to be a discrepancy: why is it that for the law of attraction to work, we must clearly know our objective

YET the catch is not to send too much energy towards that outcome, because by doing so we attach to it which will chase it away and extend too much of our life energy?

How do we set our goals clearly yet adhere to the Zen Buddhist mentality for success, which is to LET GO and detach from outcome in order to achieve it?

In my studies of metaphysics and spirituality, I've come across many contradictions so I'm here to solve them as best as I can in the most digest-able way I can. 

ANDDD the answer to success is SURRENDER. To know clearly what it is you want, to sent the intention towards them, but to also let GO after this step in the process. To be OKAY with not receiving it and giving your faith over to the higher order- to know in your heart and mind that if it's not in your divine plan, that it's alright, you accept what will come.
