Also don’t forget that nothing is stopping you from having multiple projects open at once. Each can be a totally blank slate. If you have a LOT of plugins open (with samples), there might be a delay when switching between them (i.e. activating different project windows)…but other than that, no reason to stress.
Fun fact: You can copy and paste parts from one project to another, and if the same instrument is not in the other project, it will automatically create an instance of that instrument WITH ITS INSERTS AND EQs ETC to accommodate the part in question 
I do this all the time to re-use parts in other projects.
