This is it. It's all been leading up to this.
Your whole life, from birth through growing up, from toilet training to however far you've taken your education, has been leading up to this. Your hopes, your dreams, your ambitions, your struggles, have all been for this one moment.
When you think about it, everything you've ever known, ever been, and ever dreamed has been leading up to this moment right now. From when you started reading this post up until right this very second, your whole life has been leading up to now - your reading of this sentence, this clause, this very word.
And now it's all been leading up to whatever it is you choose to do next.
