As a DBA, you are expected to be more diligent about your work, more experienced in everything you do - especially if you've never done it before, and know a lot of things about every intricacy of SQL Server. This is why many of us are plagued by the Imposter Syndrome and probably always will be. Heck, most of us can't even attempt to do the things we'd like to try on a Test box with a smattering of decent sized databases on them, in case our bosses find out we're trying something new in our spare time on their dime, even if it's after hours!
