There are small failures all the way along in most projects. You have to dust yourself down, pick yourself up and start all over again….sounds like a song! Mostly you have to look at how and why the thing failed and come up with a way of improving it. Regards Robin
A lot of research is about coming up with new ideas and some of them just don’t work. The fun bit is working out why it didn’t work the way you hoped it would and deciding what to change so that the next time it does work!
