If things aren’t coming together in the way that you would like, then that could mean you’re trying too hard to force a fit, which is never a good thing. If deadline pressures are forcing you to come up with a solution, even if it's only a temporary one, then you must slow down and take whatever time is necessary to complete your assignment. 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 it later.
