Building a curriculum vitae is a professional necessity that is too often overlooked. People tend to think ‘why bother’ or ‘I’ll remember’ when it comes to things they should be recording. Memory fades and with it the capacity to recall things that can help with job and promotion applications.
I would suggest considering buying an expanding file. Label each opening with one of the graduate standards suggested by AITSL. It would be wise to label them in order of the way the graduates standards are listed in documentation. Then as evidence of meeting graduate standards is provided, place a note about that in the relevant section of the file. Also include evidence confirming your meeting of those standards. Samples of student work from time to time may help, particularly if they verify teaching strategies and efforts. In addition it can be handy to keep a notebook into which you add jottings from time to time, for transfer to your CV.
Make sure you unload those jottings into the file possibly expanding them into a more detailed format before so doing.
As time goes on upgrade your file to consider standards for teachers gaining new understandings, proficiencies and experience. In that way your folder is of evidence is always up to date.
Make sure that as you update your expanded folder, to take out those things that are no longer relevant. They become secondary (aged) rather than primary (recent) evidence. When cleaning out the file my suggestion would be that rather than destroying documentation removed, you store it in some secondary way to be called on if necessary.
Photographic evidence confirming what you have done can be useful. With iPads and iPhones, taking supporting photographs becomes easy. My suggestion would be that you either print these photographs and add them to the folder or alternatively that you start an index on the device into which photographs can be added.
From time to time colleagues and superordinates, even parents might offer you written recommendations or references. Keeping these and adding them to your CV is important because those statements substantiate and validate what you have to say about yourself.
Developing sound methodology in relation to compiling evidence for CV purposes is a very good habit to establish and maintain.
EDUCATION, A LIFE FORCE 
Thank you so much for this, Henry. I find this post very helpful. As a young professional I find myself aspiring to do more while forgetting the achievements of the past. This post has reminded me of the need to keep a track record of my abilities and successes by documenting them. I agree with you that this is so vital.
