You don’t have to see the whole staircase, you just need to have enough courage to climb each stairs knowing you will someday end up at the top of the building which is your ultimate goal.
But that courage is only built on hope. Hope is the only thing that will keep you going even when the next step seems difficult and you aren’t sure where it leads.
Break down the ultimate goal and have enough hope to see each stage through by living every moment the its fullest knowing each step takes you closer to your destination.
Learn to build hope for small steps, then it becomes easy to build hope for greater ones. Against all hopes, have HOPE.
