Excel Personal Macro Workbook reference Book1 - vba

Question

I've finally figured out why my code was crashing. I have this set up as part of my Personal Macro Workbook so when I open a default Book1 I can run it. However, the issue is that since it's running the macro from the PMW the "Sheet.Copy After:=ThisWorkbook.Sheets(1)" is crashing.
How can I make it that the code below running from the PMW would copy the sheets into the default Book1?
Original code below;
Sub GetSheets()
Application.AutoRecover.Enabled = False
LInput:
PL = Application.InputBox("Threshold Report Path", "", "C:\Users\")
Path = PL
Filename = Dir(Path & "*.csv")
Do While Filename <> ""
Workbooks.Open Filename:=Path & Filename, ReadOnly:=True
For Each Sheet In ActiveWorkbook.Sheets
Sheet.Copy After:=ThisWorkbook.Sheets(1)
Next Sheet
Workbooks(Filename).Close
Filename = Dir()
Loop
End Sub

Answer 1

ThisWorkbook refers to the workbook with the macro.
You can refer to it by name:
Sheet.Copy After:=Workbooks("Foo").Sheets(1)

Answer 2

I think you misunderstand the purpose of the Personal Macro Workbook; it shouldn't be auto-running anything. It's not a template. It's a place to store macros that you use often, so that instead of copying the macros to different workbooks, you can leave it in one place an run it from there.
I think what you want is a Personal Template that includes the template worksheet already, so nothing needs to be copied every time you create a new document.
Create a workbook, copy the worksheet in manually, and save it as a template. Avoid auto-run code in the template as well.
