If you are toying with the idea of AP, and finding your way to these forums, and have probably read a couple books about the subject, I don't understand how you can be asking if its worth all the trouble! Its the universe!!! Its the world we live in plus infinite others. Its where and how we exist. It is literally endless realms of anything imaginable and unimaginable, waiting to be explored. Oh and then theres the fact that you can fly! And you can't die. Do you see where this could get interesting? Endless possibilities! Sorry if that seemed forceful, Im only trying to get you to see how amazingly fun AP can be, and to use your imagination to think about where you could go and what you can do.
Now that being said, Earth is the focus of our lives for now (and lives to come) so I guess if you want to look at it that way and just be a "normal" person who doesn't really care/know about AP and all this exploration stuff and just wants to live their life on Earth, then there is nothing wrong with that either. Or just do meditation, its awesome. What we are doing on Earth is amazing enough. You don't have to AP. We are all given the gift of physical life on Earth which is the greatest blessing of all. So you can't really go wrong. And the funny thing is that when you realize that the world is not static and that everything is always moving and changing and evolving and alive, you will see that physical Earth life is just another amazing form of astral travel (slightly more physical and "heavy"), and a thousand times more dangerous because we need our bodies here... hence the amazing blessing to have the opportunity to live in the physical realm.
So then that would make pretty much everything we do, in a way, "spiritual" already, without having to make any beliefs, religions, or required textbooks necessary to have a "spiritual" experience. You are doing it already, even now. And the Earth-Gaia thing we have going on here is so precious, you have to admit. And amazingly unique in the universe, it is our home away from home
But there are others, places, people, beings, games, art, music. Why not see what's out there? Your body will be waiting for you in the morning! And you will always wake up, here or there 
And for me, when I got into AP and all this about 10 years ago (in my early 20's), my view of the universe was not as big, and I had a pretty big imagination even back then. But now that the universe seems so much bigger because of my new discoveries and insights, the Earth seems so much smaller, like we are all neighbors here, all the same Earthlings (which is why we should stop fighting about everything!). I think when I started practicing AP my goal was to get away from Earth, join the enlightened ones, never to return. Now I see that it is our life on Earth that is the precious gift, and the other realms will always be there to explore.
But AP can give you proof, and only on a personal level, that you are more than just your physical body and that there is really no such thing as death. I think thats pretty profound. You don't have to take my word for it, or from some religious leader, or from some old book but prove it to yourself that you are more than just physical you. And while I'm sure meditation can lead you to these same conclusions, theres nothing like experiencing it first-hand. And at some point, I think meditation turns into AP anyways. I really don't think those meditation masters are really just sitting there for 20 hours straight. Maybe. But I bet most of em are flying through different dimensions for most of it.
I also know that you can't force AP and that it will happen for you when you are ready, although practicing it is necessary for most of us, at least in the beginning. It took me quite a few years of casual practicing before I ever got to the vibrational state (and even then it was spontaneous), then a couple more years before I had my first full OBE. And I have not had more than a couple dozen since then, altogether. Im in no hurry
But I though you should know that Im not a veteran AP'er. And I still get scared almost every time the vibes hit me! But as the others have said, AP is about conquering your fears and seeing where it takes you. I keep a very positive mindset in general, so I've never had any problems going to "dangerous" places or meeting malicious entities, because thats never been my focus or interest, or even one of my fears really either, so I've never had a problem with it. I really can't offer any help in that area. But from what I've seen, its enough to convince me that you cannot ever die from anything, ever... you will always wake up. Just don't get negative or allow yourself to become something you hate or hurt others.
My experiences have all been very positive and its been a life/mind/paradigm-changing ride over the past ten years. And yes a lot of it was scary, no doubt about it, and Im sure I'll find other things scary in the future. But Im very glad I kept reading all the books I could find and practicing now and then. Its been a true adventure and I love life so much more now knowing the things I know about the world and the universe. AP gets my endorsement and I really hope you try it out! Unless you have strong mental, emotional, or personal life issues going on, I think you will be amazed at what you can accomplish with AP. You just have no idea what you will find. I hope you find something good and not scary! And learn a lot about yourself and the world we live in. Go somewhere nice. Fly out and see the moon, the Earth from space. Listen to a celestial choir or rock out at an astral party. Create your own dream home on your own planet! Meet other people and other beings. Help someone out. Share the love. Keep a good vibe going. Blessings!
