Solitary struggle to a shared accomplishment
Building a house by yourself is technically possible, but would require significant effort and many months or years of your time.
Finding 10 experienced workers to build it with you would make the project much more plausible.
For some, building a house alone might be a badge of honor, but to most it would be a recipe for frustration and the quality would likely be limited.
Seeking out people with knowledge, persistence and the appropriate tools can amplify your efforts.
