If "discovering" your idea is a significant motivator for realizing it, I guess thoroughly scratching the creative itch first might be risky.
This is probably it's own Goldilocks or yin/yang sort of thing? Sometimes I quixotically wander into implementing a project, hook myself with sunk-cost fallacy a fraction of the way to the finish line, and would have ultimately considered it a blessing to scratch the itch without touching implementation.
