>I run my own VPN and share it with a few other people.

How confident are you in your VPN server configuration skills? Gaining access through mis-configured self-hosted boxes is the easiest attack vector usually as most people who self-host aren't experts in the software they are using leading to leaks. Besides that, do you keep a list of packages installed on your box, open ports, etc? How about security patches and regular updates as well as auditing access logs to ensure no one gained access to your box?
