I've had my PPL for just over a year and was really conscious of not letting any bad habits creep in. I do the same as you Warrior Chief and do some exercises ...... pax love it!!! Went up the other day and did a couple of steep turns and a glide approach just for the shear fun of it all.
Mind you, I do find myself doing things I shouldn't be like track crawling rather than the nav techniques I was taught <img src="mad.gif" border="0"> . An hour with an instructor soon sorts it out. The trick is knowing when you need a check ride <img src="wink.gif" border="0"> .
