At the last place I did sysadmin work, this was basically how I functioned. Just about everything was done to prevent having to use google, stackoverflow, etc. It was absolutely amazing in terms of learning and gaining confidence in the tools and documentation, etc.... but nah. After about 3 months of that, I gave up. It's possible, but it led to so may "time wasting" rabbit holes in trying to figure things out. I thoroughly enjoyed it, but in hindsight, it probably wasn't the best use of time while at work (and should be frowned upon if management ever suggests it)!
