$ GO_PATH is the environment variable that defines where all your Go related things will be, including

All the libraries you download.
All project source code.
All binary files resulting from the source code compilation of your projects.

Notice that this is different from most other languages, which has a folder for each project and saves the files / libraries / binaries in the folder of their respective projects.

See the example file organization from official documentation :

bin/
    hello                          # command executable
    outyet                         # command executable
pkg/
    linux_amd64/
        github.com/golang/example/
            stringutil.a           # package object
src/
    github.com/golang/example/
        .git/                      # Git repository metadata
    hello/
        hello.go               # command source
    outyet/
        main.go                # command source
        main_test.go           # test source
    stringutil/
        reverse.go             # package source
        reverse_test.go        # test source
    golang.org/x/image/
        .git/                  # Git repository metadata
    bmp/
        reader.go              # package source
        writer.go              # package source
    #... (many more repositories and packages omitted) ...

Now, if you still think you should set the $ GO_PATH to your project folder:

1 - Navigate to the desired folder

2 - Enter the command:

$ echo $PWD >> ~/.bash_profile
$ source ~/.bash_profile

Remember that you will have to do this every time you change the project, since the commands in Go will search everything on the page you set $ GO_PATH
