It sounds like you know when you are lost
Not necessarily the case - many years ago, cutting a long story short, I ended up following a student round a solo cross country in another aircraft, he flew the first leg and a half perfectly and was BANG ON TRACK, and on time when he "got lost", had he he kept on his planned heading and monitored his timing I am sure he would have been fine, as it was it was surprisingly easy from close line astern to tell the second he was unsure of his position!
