How can one…get a post-Doc position/decide in which area to specialise/publish enough etc.?

from tinizini.com

Beginning with next week and usually on the last Friday each month, I will post interviews of young colleagues asking them about the "secret" of their success, hoping that this will help filling the gap between students and ex-students and full professors who seem beyond reach.
I will ask questions such as "What did you do right to land in your actual position?" and "What would you recommend to younger colleagues?", but also "What do you
think needs to be researched in your area of specialization?" and "What are your research strategies?".

What would you like to know? Suggestions for questions are welcome!
