Great words by JD!
When I first started estimating work, I found I was almost always woefully short, so I started doubling my estimates. Still short, so I started multiplying by 4, then by 8 (yes, I was often off by a factor of 8). Still often short, so I changed to estimating the number of lines of code I'd write and using that as the number of hours I'd spend. Rarely was I short after that. This DOES, however, require that you know enough about the project to be able to estimate the number of lines of code... One other comment - I once took a fixed-bid contract. I quit keeping track of my hours once I was making under $1/hour... I was off by at LEAST a factor of 20, probably more (this was VERY early in my contracting life, and I was only charging about $25/hour back 30 or so years ago). So estimating is hard, and getting the number within a factor of 2 is probably impossible without a VERY good specification.
