Is there a Buddhist saying similar to' don't forget your initiative' in Buddhism, seeking the original sentence and explanation?

Don't forget your innovative spirit, so as to achieve your ultimate goal. Everyone has a pure and kind heart, but the world is like a melting pot, which gradually blinds people. Especially in troubled times, it is most difficult to stick to a pure heart. People must always adhere to their inner purity and kindness in order to achieve positive results, be worthy of the world, be worthy of others, and have peace of mind.
