It's generally a good thing to be reminded to upgrade. Regardless of whether or not a certain release is considered Long Term Service — if there are major unresolved problems with the platform or supported software that are not fixed — then it will be necessary and appropriate to upgrade as soon as the "nag" issue is fixed in the next release assuming other problems are not being introduced at the same time.
Otherwise if everything "works" and there are no major security issues, then it's not such a hurry, but plans should be made to upgrade in any case.

First thing to note is that Ubuntu 18.04 is a Long Term Service release, and will be supported until 2023. So no matter how naggy Ubuntu is, you don't actually HAVE to upgrade at this point.
