This is used during the character generation process. It leaves you with a trace of what the character did throughout his or her life, and what was learned at any given time. It is a tool for creation, but paints a good picture of the character's history as well.
Fill in the skills learned for each year by putting a +1 for every point spent. Enter skill names in the far left wide column, and note the first year the skill was learned by drawing a line to that column. Put totals on far right. Copy totals to main character sheet as well. It is convenient to record profession changes at the top, and to record reasons for these changes in the notebox at the bottom.
