Yes. The first thing I did was create an extremely detailed specification document where I wrote down what I wanted, how I wanted it and where I wanted it. For me, that’s the most important foundation. With that, you’ve already done a lot of the work. In fact, I even go so far as to write pseudocode in some cases.

From there, you use that as your ‘bible’ and stick to the script you’ve written for yourself. Obviously, as you go along, unforeseen issues may arise, and in that case, make a note in the spec, find the best approach, and carry on.
