Creating projections
I like the idea of making projections about when things will happen and planning in advance. I have recently been working on a timeline to FIRE (Financial independence / Retire Early) so that I can at least have a rough idea as to when I might achieve this. Like any model used to predict an event, the accuracy of it is dependent on the inputs. The more variables you try to capture, the more closely it resembles what is likely to unfold. Then there is of course the need to update it as time goes on and new information becomes available. Life can’t be predicted, so a timeline to FIRE can never be 100% accurate but it at least gives you a good guess…
