I tend to give my all to the roles I take up towards the start and once it becomes routine, I get bored from those tasks easily, even in situations when I enjoyed those roles initially. The boredom usually lasts to the point of frustration and mental upset however since I discussed it with my managers and they modified my roles and responsibilities, it wasn't as bad.
This happened in an internship I took up previously and the job I am currently doing. Will the multi project nature of the consulting firms be suitable in this case?
