The short answer is unfortunately yes. I have never seen (or had) a student or postdoc who has done well and NOT worked hard (trust me I have seen a LOT). When I was seriously doing experiments (not that long ago), my experience was that I had to give every fibre of my being to find anything that was really new. So I suppose putting in long hours is kindof important, but I have come to realize that there is a specific time when one needs to really, really work hard. And that is the time time when everything is going really really well.
When one is just starting out, and simply "fooling round", trying to find something interesting to do, perhaps it is not that critical to work hard. In fact it may be argued that one should not work that hard during this time. This is a time that is typically filled with disappointment and frustration, and perhaps a cavalier attitude is best. Try your best and come what may ("whatever" as teenagers now say). Trying too hard will only lead to greater frustration, so stay focused but loose.
But when you get on the right track after a few months and in your mind's eye can see what mother nature is really saying, that's really the time to work really really hard. This is the time when the methods are all working, the constructs are all made, the experiments are all lined out (pretty much), there is only one thing to do. WORK WORK AND WORK. Get it done. There will be lots of lazy afternoons afterwards. Undoubtedly there will still be setbacks and frustrations (that's how this works, OK), but in the end the pleasure is - as Feynman famously said - in findings things out!

The PI Blog
This blog exists because my wife seemed a bit tired of being the only recipient of my random pontifications on life and Science for many years; and gently encouraged me to vent in a blog instead. From time to time, I put down thoughts that occur to me as I naiively stumble through a life in Science - bestowed upon me by accident (literally!). Please keep in mind that these musings are rather obvious things of little or no use to anyone, and are certainly not personally targeted in any way, even though they are obviously derived from my experiences. OK, enough said.
