If something is a HUGE seller for you and it is not evergreen, then for sure it is worth updating frequently yourself or by hiring a Virtual Assistant to help. I am not saying you should make everything evergreen or not, just that if you want to keep it truly passive it is best to pick something that is going to stay “in fashion” for quite a while.
Numbers nerd. Guilty. I have always completely geeked out when working in Excel and creating spreadsheets that provide the information I need quickly and easily. I hate wasting my time in activities that do not add value and focus my efforts on being efficient as possible. My desire is to help others do the same! The files I create are tailored to the spreadsheet novice and do all the calculating for you. They are also always formatting to print out just right in case you need a hard copy.
