Consider creating a "master" CV

Consider creating a "master" CV which includes all of the relevant sections.

Once you identify a job opportunity you want to pursue, use your master CV as the starting point and tailor it to the specific opportunity - even it this means chopping 'lots' out.

In time, your master CV may grow to 4 or 5 pages however, don't be overly concerned - it will contain everything you ever did.
