I don't see any need to "finally" anything. I have done a number of start-ups, enough to retire on though none spectacular, and probably fewer than you depending on how one counts them.
I am doing a PhD part time, and running a few local groups (including the local inventors' club), and keeping some powder dry, ie time and cash on hand and networking, so that if another opportunity arises then I can follow it.
