"All important battles are fought within us" That's why you need a sword sharpened by determination and courage. The skin full of scars and some wounds without closing. Calluses on both hands of wielding the sword and worn-out boots soles of walking. In exchange you'll have your eyes full of world and a mind filled with ideas along with a tongue capable of expressing them in a wise way. Such is life, you can undertake the journey or stay in home safely, the decision is yours, I made mine a long time ago.
