Perseverance & Patience

Perseverance & Patience, is what I am learning. Edison performed 10,000 light bulb filament experiments in a 1.5 year period, before discovering the magical formula (thin carbon in a vacuum). How often have I given up well before 10,000 tries, or 1.5 years? What success or benefit was lost when I did that? My current goals demand patience. What person or project in your life deserves more patience and perseverance?
