Don't ignore the crap students with no aptitude an attitude and who mess you about. The marginal weather, the ropey aircraft and the huge responsibility involved.
Don't forget that the career or hours building instructors will hate you for your casual labout - don't really need the money, do it for fun - status. You undermine them.
Consider that teaching S&L, Circuits, Area Nav blah blah can get very very dull after a while. Loads of fun for a while but maybe a but repetitive and limited over a number of years...
Good luck though. Its better than NOT being a pilot/instructor.
Cheers
