As a graduate student you have been working for Dr. Supervisor for four years. In the initial years the research went smoothly. But in the last two there were numerous problems and delays. You have spent a lot of time pursuing various hypotheses suggested by Supervisor and think the setbacks were due to the multiple avenues that Dr. Supervisor wanted you to try simultaneously. You are concerned that Dr. Supervisor now questions your ability.
Now it is time for you to graduate and you are worried that the recommendation that Dr. Supervisor writes will reflect only the recent setbacks. Also, Dr. Supervisor wants you to aim low. That is, he wants you to apply for less demanding jobs and positions. You want to aim high.
How should you handle the situation?
