I can't speak for others, but for myself, my goal with Astral Projecting multiple times is just to return back to that state of mind. It really helps me in clearly unnecessary or negative thoughts away and focusing on that which is important.
I believe everyone has their own personal goals. But you should feel accomplished that you have been able to do it an abundance of times because many are still working to experience it for the first time.
Do not lose hope, your goal will be revealed to you one way or another. Give it time.
