Unfortunately, this question can only be answered by you, because at the end of the day, you don't want to blame anyone but yourself or give credit to anyone but yourself pending the results. I wanted to join since I was 13. I even remember trolling the USMC website and telling my dad one day, "I'm going to join the Marines when I get older!" The response I got in return was, "No, you're not.." in a concerned stern expression. After I graduated, I was working in a box factory, if you can believe that, and I HATED it! I had a serious 3 year relationship going with my high school sweetheart whom I was absolutely crazy about spending the rest of my life with and yet, I felt so miserable and unfulfilled at the same time. At my girl's family get together another year later, I again mentioned how I really wanted to join the Marine Corps. I was shot down with so much negativity, I immediately regretted opening my mouth. With it constantly in the back of my mind, over the following months, I eventually had to decide, risk losing the woman I love and possibly, quite literally my life, or live with the shame and regret of not doing something and wondering where I would be had I done what I so passionately wanted to do for myself. I decided I couldn't live with myself if I didn't and if me and my girl were truly meant to be together, it would work out in the end. Needless to say, it was the hardest, most hurtful experience I have ever gone through and my girl (now my wife) would agree, but I don't have to live with a "what if" scenario for the rest of my life. And in the end, even if things don't go according to plan (and they won't) and as long as goals are set and one makes it a priority to achieve them one way or another by living up to their expectations, then there won't be any regrets. It was the worst 4 years of my life, but worth every second of it and I don't regret having served. I'm happy where I ended up and can now only imagine where I might be if I hadn't joined and it's a scary picture. The decision is yours that you will have to live with. Sorry about the novel I just wrote, but figured It might help sharing my experience in making the decision. Good luck with whatever path you choose.
