Home tab macro

I have an excel file that has about 20 different worksheets in it. The first sheet is a list of all the other sheets with hyperlinks to easily switch to each page. What I would like to do is have a macro in the quick access toolbar to jump back to the first tab. I managed to get it to work using this simple macro

Sub Home()
ThisWorkbook.Sheets("Home").Activate
End Sub

, however it stays linked to the original workbook if I re-save the file with a different name. I need the button to be linked to the file it is in if the file is saved as something else. A macro might not be the best way of accomplishing this but I don't want to have a cell on each page hyperlink back to the home tab as that would be redundant and also print on the page when I print a worksheet.

I am using this for work and have it in dropbox so my colleagues can access it also. Will the macro still work if the book is saved to dropbox and used on a different computer? Thanks for the help
