You can always ignore data that you have, but you can't use data that you don't have.

Be careful about spending resources on collecting useless data though.

That is a very good point. If you have data lying around, you might as well take a look at it, but think two and three times before you spend time and money collecting new data.

this is more what i'm getting at - collecting more data is good, but just having more data isn't necessarily 'good'
