Hi ISamson,
I am currently attending a university for Cyber Security where we are encouraged to "hack". Our network is completely separate from the rest of the campus and we only use virtual environments. So we can wreak havoc when doing Red vs Blue exercises. I also intern for a large private sector company that allows for some pentesting where we are actually trying to break into whatever our target is. So in time, I think you will find plenty of places to stretch your wings and have some fun. For a real challenge (at least imo) go to hackthebox.eu. As many others have stated, attack your own devices. VMs are your friend! You can clone and reset anytime you break something. Good luck!
