I am quite new to linux and have had issues surrounding every program that I install. Basically, anything that is placed outside of my home directory requires a sudo call prior to opening/executing. I cannot write to files, open usb devices, or run programs that exist outside of this directory (specifically, above this directory).

I know this is a privilege problem, but I come here to ask how this can be permanently stopped. How can I configure things such that when programs are installed I do not have to manually find the executable and change its privilege requirements?
