What do I advise? Forget it all. Don't be afraid. Do what you get the most pleasure from. Is it to build a cloud chamber? Then go on doing things like that. Develop your talents wherever they may lead. Damn the torpedoes - full speed ahead!
If you have any talent,or any occupation that delights you,do it, and do it to the hilt

I went for a walk outside. Maybe I was fooling myself, but I was surprised how I didn’t feel what I thought people would expect to feel under the circumstances. I wasn’t delighted, but I didn’t feel terribly upset, perhaps because I had known for seven years that something like this was going to happen. I didn’t know how I was going to face all my friends up at Los Alamos. I didn’t want people with long faces talking to me about it. When I got back (yet another tire went flat on the way), they asked me what happened. “She’s dead. And how’s the program going?” They caught on right away that I didn’t want to moon over it. (I had obviously done something to myself psychologically: Reality was so important — I had to understand what really happened to Arlene, physiologically — that I didn’t cry until a number of months later, when I was in Oak Ridge. I was walking past a department store with dresses in the window, and I thought Arlene would like one of them. That was too much for me.)

The first principle is that you must not fool yourself, and you are the easiest person to fool.
