"Using these toolkits is like trying to make a bookshelf out of mashed potatoes"

This quote by Jamie Zawinski is an amusing method of expressing the difficulty of using specific toolkits. It implies that the toolkits are so hard to use that it would be simpler to make a bookshelf out of mashed potatoes than to use them. This is a metaphor for how challenging it can be to use certain toolkits, as mashed potatoes are not an appropriate material for making a bookshelf. The quote is also a tip that it is necessary to pick the right toolkits for the task, as some may be too challenging to utilize. It is likewise a suggestion to make the effort to find out how to utilize the toolkits properly, as this will make the job easier in the long run.
