Be very focused. Do your homework so your research and claims are unassailable. Make sure it is bulletproof and then make sure you are really focused. The thing I find is that the issues are usually so large that you try to cover a lot of ground. That's a natural impulse.

The difficulty is the levels of secrecy we had to maintain around the project at all different times.

One of the top challenges is the fact that you are dealing with survivors.
