Hahaha, I completely understand the struggle.
I work in a research lab here on my college campus, and I do a lot with DNA purification and mRNA production from the purified DNA. For example, I've been doing a lot with Sf9 (insect) cells where I've been infecting them with a specific baculovirus to produce my desired protein for later purification. These things take weeks, and if one little thing goes wrong (like if the cells get contaminated), then you're set back at least a week, if not more depending on what step of the process you're in.
Science is a constant struggle.
