Cayra
A useful way to model aspects of life, learning or business is through the use of mind maps. One could use pen and paper, which is great, but it is more effective to create a digital version of a mind map through the use of some software. A great tool for this job is called Cayra. I have been using it now for about six or so months and its a great way to visualise things and allow your mind to see things clearly. It does require .NET 3.0 to run.
