emacs lisp: supplement folder the initial turn sub-folders load-path

if i have folder structure set adult this:

~/projects
    emacs
        package1
            package1-helpers
        package2
            package2-helpers
            package2-more-helpers
        package3
            package3-helpers

how i supplement folders:

• ~/projects/emacs


• ~/projects/emacs/package1


• ~/projects/emacs/package2


• ~/projects/emacs/package3

...to load-path .emacs file?

i fundamentally need brief involuntary chronicle code:

(add-to-list 'load-path "~/projects/emacs")
(add-to-list 'load-path "~/projects/emacs/package1")
(add-to-list 'load-path "~/projects/emacs/package2")
(add-to-list 'load-path "~/projects/emacs/package3")
