How can I go from an idea to an MVP in minimum time? What are the absolute necessary steps?

Considering I'm a solo dev, how can I go from idea to design to development to an MVP. A detailed roadmap would be preferred. Also, please answer this in a technology agnostic context.

There are no good resources on web on this topic for a solo dev. So, I'm asking the Hashnode community to answer this or provide me with good resources.
