Best way to handle work log listbox output in GUI?

Hello, thanks for reading this,
What I want to do is set up a listbox that outputs a work log of what I do in the GUI. What I do is output strings to the listbox whenever I do a certain task. My problem is whenever I output a string, it overrides what was already there.
What I do is set the handle for the listbox to a string value whenever I output a new string using set(handles.listbox, ...), and I know this is the problem because I'm continually setting the listbox to a new value. My issue is I don't know how to dynamically add to it without deleting what was already there, it seems wasteful to continually delete and populate it.
What I was thinking of doing is adding to a continually existing string, or concatenate several strings into a longer one using cells. I would still be continuously deleting and populating it, but I wouldn't know how else to do it. Is this the best way, or is there something better to do I'm not understanding?

"it overrides what was already there" that's the way Matlab works. You need to
Example:
figure
lbh = uicontrol( 'Style', 'Listbox', 'String', {'line1','line2'} );
str = get( lbh, 'String' );
str = cat( 1, {'new line'}, str );
set( lbh, 'String', str )
str{end+1} = 'bottom line';
set( lbh, 'String', str )

I find it most convenient to use a cell array of strings as in the example I added to my answer.
