There is a wide chasm between you and the "promised land." The realization of the deepest wish of your heart.
You have to jump across it, unassisted. If you fall short or stumble, injury or death is likely to result.
Why jump at all? It's safe on your side. This is true enough—you don't have to.
Your dream will eventually become so important that you're willing to risk your safety for it. There will come a time when there won't be a choice about it anymore.
Now that you know what you have to do, you must summon the courage to jump with total abandon. It's a complete letting go of the known world. You can't look back. It's 100% or nothing at all.
It could take some time to do this. Survival instincts kick in. Rationalizations of why you shouldn't do it start playing inside your head, and you may decide to back off.
But something compels you.
We must trust that something and go.
