Building something in 100 hours that satisfies a class of problems but will only see use once is definitely not smart. It's called taking advantage of your employer to satisfy your own curiosity. Do that in your free time of your job is not one where that solution will see millions of uses (meaning you are not working for - depending on decade we are talking - Bell Labs, IBM, Microsoft, Amazon etc.). If you are that good but work at a regular company, build an awesomely good script that is maintainable by even a mediocre programmer that comes after you and spend the other 55 minutes of that hour doing the next task. Then go home when everyone else goes for lunch without anyone noticing because you did the work of 2 people already anyway. If you have a good boss they won't care and give you awesome life work balance that you definitely would not get at Bell Lab, IBM, Microsoft or Amazon because they know how to exploit your drive and passion for their own good. No you don't make enough money to get that time of your life back.
