Challenges... they can be very painful. Yet without challenge, we remain shallow. Wisdom does not come without a price; and the price of wisdom is not cheap.
Passion... that comes from within. Many an action is rooted from passion. Passion - that one things that drives living. Do you live just because.. or do you find passion in living? Without passion, I find life grey-scaled... and when uninhibited, each trickle of such passion slowly bursts forth with such fortissimo - and color fills even the simplest things and notions in life once again.
