I think the best project to try is the one that you have little to no knoludge of. I find sometimes the best way to learn is by failing. For myself; i hate the feeling, and failing isnt somthing that I do well. Pushing through setbacks strengthens your abilities and produces a new confidence that anything is possible. Also you can bring in an outside perspective to a project that isnt typical to that field or group. When the project is complete; you look back and realize how far you have traveled! At that point the wealth of knoledge can be quantitatively measured. When we streach beoyond what seems possible, dig in a little deeper, and strive to become a little better than we are; at that point we grasp the intangible, at that point we define ourselves. Its thoes small victories that give birth to new innovation,define generations,and forges a way for everythings' future. If you stand up and tackel the unknow, brush off the ridicule of ignorance,and get crazy enough to defy logic itself; I belive thoes minuscule moments in the history of humanity are the very iota's that allowed God to see the future of man and understand his creation is 'good.'
