Although generally happy, I've just started my second year and feel I should have accomplished more in my first year. I've got a few results but nothing spectacular and feel at this point I should be churning out hundreds of results. Any advice?

John, don't worry! I'm coming towards the end of my 2nd year and although I have some reults, none of them are what would be classed as 'final'. Admittedly, I have had some bad luck this year, but a PhD is a learning curve. Don't worry, all will become good, and if not as long as you can explain why experiments didn't work you should be fine.
