You Decide on the Ending Before You Set a Goal, Right?

In English, when we use the word beforehand, we're just saying before that thing. So if you've already decided on the outcome beforehand, then it's simply a decision that you've made. If I decide that in my mind, I'm going to do it no matter what it takes,. Even if I wake up and I'm really tired. And now I have to get to that result. This actually works very differently in your mind, because you're not giving yourself the opportunity to fail when you set a goal like that.
