Do you believe in free will?

This question always sparks a good discussion. While there is a wide variety of perspectives on a spectrum, do you believe in free will or are you inclined to believe that the actions in the universe are [pre]determined?

#1 I'm not sure if I believe in free-will or not, but I do believe that even if free-will exists, people don't always have access to free-will.
#2 I believe that things like addiction, manipulation, and perhaps other things as well, can all eliminate the option of free-will.
#3 Furthermore, I would love to know peoples thoughts on that.

I have never been told a satisfactory definition of 'free will'.

I should add the following, though

I've read several books that deal with this topic, and from reading those I can tell you that I don't know the answer. Although I don't think you can come up with an objective answer, you might find an opinion that you believe to be true. I think that we are making free decisions. I also believe that some divine entity knows what those decisions will be before they are made. For those of you who don't believe in God, you can choose one of two options; 1 is that you have free will and 2, is that you don't. The choice is yours.

I would say that there is always free-will, because, you don't **NEED** anything per se you just want it, like, you WANT to live, and if you WANT to live, you NEED something to achieve that, but it all starts from a WANT, so, therefore, there is nothing you NEED, there are just things you want, that you can will yourself not to want... like, for example, someone hires you to do something and gives you the money before you complete it, true, you will WANT to do it so that you don't break their trust and/or the law, but you don't NEED to, so, you have free-will, always, no one can ever FORCE you to do anything.

sorry about the insanely long explanation lol

My two cents on the questions
1) quantum physics is not deterministic, and one can't rule out the possibility that some quantum effects take place in our brains,
2) even if the physics were completely deterministic, the picture is only complete once you specify an initial condition. One could argue that all the decisions were freely taken during the initial conditions.
3) that being said, I still haven't be given a satisfactory definition of 'free will'.

You can do what you want but you can't want what you will.

@tourdivoire to further the discussion, let's use definition two from Merriam Webster:

"freedom of humans to make choices that are not determined by prior causes or by divine intervention"
