but everything............ but everything.............
is built one single step at a time.
Those steps may be big or small, painful or happy, stressed or relaxed, difficult or easy.....
but if you seek not to skip the steps, or jump over them, or be negative about them, then you move - one step at a time.
You may balk at a particularly dicey-looking step, or cry before one, or hesitate because you are apprehensive about something. But step you must, and if you do, and hang in there, no matter what - without looking back - it will be easier for you to negotiate the steps by and by. They don't get easier, but you find them easier just by carrying on...
