I am not sure to be able to describe my creative process ... sometimes I have an idea for a new software, sometimes I think it is not good or it is just too difficult to develop ... sometimes some months after I first discarded the original idea it brings back to me, this time with a new energy. This is exactly what is happened with "project grow":

The hardest part is the first one, "planning". If the planning is good than the development is fast and clear, not easy this is sure but you can always see the light at the end of the tunnel (and this is very important when you have to develop a big project from scratch).
In the morning I purchased new pens, new books, new papers ... everything physics, not bit or bytes, not a PDA or a project management application, just the old way to plan things, with stencils and papers. I find this to be the best way to completely concentrate myself on a new project.
