For a brief period i could feel you are talking to me directly! Yes, completely agree on the task syndrome.

However, just to add to some tips you have already shared, would like say that i would be great if to do lists and all work that you do has a direct link on the Goals you have set for yourself and your business.

If the Goal is for the business but not for you then you can delegate it.

If it is for you but not for your business, schedule it in the compulsory off day that you should take every month.

If it matches both — add to your to do list and do it before version 2 is ready;)
