That all depends on how you feel about ice sculptures. Maybe only a few people see it before it melts, but that doesn't matter. The skills gained in striving towards excellence are not ephemeral. Even if the product goes nowhere, no one can take away what was gained in the process.

And if the process is pure tedium and you learned nothing about yourself or the tools throughout it, you should try to create the tools that do inspire you to perform the tasks that don't. Manually creating a production build is boring and you rarely learn anything, but creating a good task runner can be incredibly satisfying.
