If things aren’t coming together in the way that you would like, then that means you’re trying too hard to force a fit. This is never a good thing. Even if deadline pressures are forcing you to come up with a solution, even if it's a temporary one, you must slow down and take whatever time is necessary to dismantle and reconstruct again. This could make a supervisor see red, but you need to ignore that because the simple truth is it’s more cost-effective to get things right the first time than it is to go back and try to fix them later.
