Eureka breakthrough idea!

For the past 3 days I've been at the research centre (11am starts) trying to think of an idea for the PhD topic. My original idea brought forward was not interesting enough and needed to be sexed up paraphasing my supervisor in charge. In the 2 days prior I was dreaming up other ideas, but it was only until the third day (and final hours) did I realise how to sell the original idea I had. Now I'll need to write a brief motivation for it. Shouldn't be too much of a problem now.
