So you believe in destiny? I have to say, I don't think the universe has any particular plan.
Destiny is a strong word, but fitting I guess. To say that the universe has a plan is to anthropomorphize it though, which is kind of misleading.
I just see it this way: from a purely physical point of view of the universe I'm convinced that everything is deterministic. Even if you don't think quantum mechanics is deterministic, on macroscopic scales everything certainly seems to be. It's wildly chaotic, even at small scales, but it follows predictable events. If you set a system up in exactly the same way twice, the exact same outcome should result. It's hard to find free will in that, right? Your brain is nothing but a very complex system.
You could probably find some argument that some unpredictable quantum effect
[1] has an effect at macroscopic scales, but even if you could I'm not convinced it matters. If it's not determinisic, what is it? It has to be random, right? That's still not free will. Remember, we're leaving God and religion out at this point, so you can't just say that God mysteriously makes quantum effects manifest in some free will (which would be kind of internally inconsistent with the way I've phrased it anyway).
From a religious point of view: God knows what's going to happen and He set up the universe that way. I never have a choice in anything since my decision is necessarily already made. Again, no free will.
You might could then argue that God doesn't know what we're going to do, but that flies in the face of a lot of established things in Christianity. He's stated to know everything and predict (and manipulate) people's behaviors and reactions to things, so... does He only have a pretty good idea instead of certainty on what we're going to do?
Alternatively, you might say that we have free will but God already knows what we'll choose. That's... not free will in any reasonable sense.
So, no, I don't believe in free will. Everything that will happen is set in stone and there's nothing to be done about it. I don't let it bother me though, since
I don't know what's going to happen, so the illusion of free will is good enough.
[1] - Also note that I don't believe that even currently unpredictable quantum mechanics are really random. I'm of the mind that it's a simple limitation on observation that is probably insurmountable. While we may never have a good enough understanding of physics and the ability to measure it, I believe all quantum mechanical processes are fully deterministic and following exact processes with no randomness whatsoever. The underlying physics might just be unobservable because they're too fundamental. Note that while this means that things might as well be random sometimes as far as we can see, the point is that if something follows internal but hidden rules then its results are not really random.
I'm aware that there is some proof that this can't be the case, which I really need to brush up on since it was written by someone who is much smarter and more versed in the field than me.
