How do you keep track of querys using hints.

Hi, one question please , I had seen is necesarry to set hints to improve performance of specific queries, but
the load of the data can change and the hints can become harmful.

I don't know how can one keep track of more than 1,000 queries with hints.

When you set hints in some queries how do you keep track of them, you apply hints only through views?
you periodically check?
you don't use hints except a very very few situations? etc.

Thank you
