Sloppy approaches, forgetting to swtich
tanks until the aileron to keep the plane level is
unmistakable, not identifying stations, and what bothers
me the most, is confidently navigating right down the
center of the wrong airway. How, you ask? Simply by
putting my finger on the map 3/4" from where it should
have been, and then reading off the headings, intersections,
everything incorrectly from that. I'm sure my instructor
knew what was going on, but I only found out when ATC
kept asking me why I was so far off the airway. (these
airways were close enough in distance and angle that my
error only became obvious to radar after many minutes
flying.)

I use a highlighter on the airway, fixes, VOR frequency blocks,
departure and destination (and alternate, where applicable). Any
information on the map along my route of flight, I highlight. I makes it
easier to find quickly.

I talk to myself as I touch the radios to change frequencies, reminding
me to identify after tuning.
