Actually I just realised that the already existing 3 text boxes (green, red and blue) explain the purpose of the coloured arrows.
As in the green box explains what the Actualism method is. The green arrows are all about the successful application of the method.
The blue box explains the process of seeing the silliness of feeling bad so that one is back to feeling good. The blue arrows demonstrate the successful application of the tools in order to get back to feeling good.
The red box describes that the goal is the minimisation of both the bad and good feelings and a maximisation of the felicitous feelings. The red arrows demonstrate a situation where one is trapped within a feeling pattern and takes steps to minimise or navigate out of it.
