In the Linux world, as others before have said, "everything is broken".
If you are a developer or sysadmin doing anything of any significance then your ability to reach your goal is defined by how quickly and easily you can recognise and find workarounds for broken stuff.
Actually, not everything is broken, but so much is broken that it feel like everything. It's the broken stuff that will take your time. The stuff that isn't broken will be easy and will happen quickly.
So the faster you can jump through Linux's never ending minefield, hot coals, machine gun nests and shards of glass, the faster you can get productive work done.
Wanna be productive? Get good at seeing and sidestepping and fixing broken stuff.
