I just got the idea in my head that since a pilot is always learning that maybe we could have a thread on lessons we have learned either by doing something right or wrong while flying. Experienced and new can share. Some of it may be a no-brainer to the experienced guys, and some of it may be over the heads of the new guys but I think it could help us all. If it is a good idea maybe the mods can make it a sticky.
I'll start. Flying back from Minchumina lake for my 2nd solo XC last Friday I approached Fairbanks prepared to make my approach to the smaller strip (2R-20L). Tower decided to try and confuse me and told me to enter a right pattern for the big strip (20R) then at the last minute asked me to switch runways to 2L. I landed on the big strip and then ground control proceeded to give me a bunch taxi instructions which I had only read about in ground school in order to get me back to GA parking. At that point the only taxi instructions I had ever received was "taxi to parking via ramp."
Lesson Learned: Just because you think something you won't have to use something you learned in ground school doesn't mean you won't have to. Don't get comfortable with the normal operating procedures at your home airport because they can change without warning.
