This is the ultimate statement on self-efficacy and the power of mindset. It cuts through all external factors—resources, timing, or difficulty—and places the ultimate control squarely within your own belief system.
If you approach a goal with the fundamental assumption that it cannot be done, your mind will actively search for evidence to prove that belief right (finding obstacles). However, when you commit fully to the possibility ("I believe it is possible"), you unlock creativity, fuel your perseverance, and actively seek the path to success. Your belief isn't just an opinion; it's the engine of possibility.
