I continue to muddle through but I make a point of capturing my muddlings on Confluence so the next poor sod has at least a strong starting point.

The great thing about writing stuff down is that those that know better can see where I'm going wrong and correct any incorrect assumptions.  One of the problems with muddling through is that, although you will produce something that works, you are never sure if you have produced something that does it the hard way.  Where is the trusted source of knowledge on the subject on which you are muddling through?
