1) You are sharing a work account with your wife who has her own work universe. So when she is working on an article about the "ultimate cloud deletion tool" you will get dragged into her experience without knowing it.
2) you seem to (in theory) have no problem separating your work files from your professional files.
3) you let strangers (yes they are people you are working with but) access accounts that have files that you need for more than the moment. box.com should be no more than a ftp server for transferring files and you should see that the files are deleted after the other party gets them.
4) you don't seem to have any home backup system even though your livelihood seems to be dependent on the availability of that data, not to mention your personal data. dropbox should be the backup of the backup.
