Spent 3 and a bit years instructing, CFI for the last 2. Enjoyed it immensely, yes financially it was a struggle but wouldn't change the way I did things. Spent a year in a holding pool, didn't pay for my type rating, don't have a reduced salary ( although to be fair its not a huge salary), and at time of writting with my sim check tomorrow I haven't as yet signed a training fees agreement, and its flying a jet. All the instructors that I know have got airline jobs and its becoming sooner rather than later. You learn so much about flying as an instructor, maybe not necessarily airline flying but the experience you gain and making those command decisions on a daily basis will hold you in good stead. Plus its great fun!
