That's very true for me too, many many things have happened in real life, and it seems a lot more than four years. In fact, I think I miss a lot those "old times".
Many choices done, some proved very bad, but in the end it could have been a lot worse, so I don't regret them too much. Things are going mostly o.k. now.
PhD finished three years ago, real working life began. Still in the far corner of Brittany, but now working in the IT departement of a bank (instead of doing R&D as I would like). My daughter grows up, already 5 years old.
And you, how are things going ?
