"It isn't the mountain ahead that wears you out; it's the grain of sand in your shoe." Anonymous
Every mountain in life is climbable. There might be adjustments that need to be made in order to reach the top but it is doable. We just have to stop every once in awhile and shake out those shoes getting rid of anyone or thing that acts like that grain of sand and holds us back painfully.
For us brain abscess and canser are our mountains. I conquered brain abscess and all of the stuff that accompanied it and we are near the top with canser(I spelled it wrong on purpose). We have shaken our shoes enough to fill a sandbox and wow what a difference it is to walk in cleared out shoes.
Some people just stand in awe of their mountain(s) and are scared to take them on but you can't let the overwhelmingness have control. Own your mountain and when you reach it's peak you will be amazed by the view.
