Look at it as 500 small projects...all will have to be done at some point, so if times are bad, go and make something else for a while..I dunno... say a cleat or a frame or a pair of backing pads, then come back to the problem piece.
Whilst working on another bit your brain is very likely to 'chunter' on the original issue and will resolve it. May take a day, week or even longer.
Also remember that there is more than one correct or right answer to any of these boat building problems. So don't worry if your idea is different.
Most of all relax...
Frame of mind is everything.
