We all have this question. Does free will exists?

As human beings we are capable of rational thought and self-reflection, we imagine ourselves to have "free will," which makes us distinct from inanimate objects and animals. We believe we are masters of our own destinies, because we can choose to conform our actions to our desires (we can "do what we want").

However, if our choices are determined by our desires, then the freedom of our choices really depends on whether our desires are "free" in the first place, doesn't it? If we follow the origin of our desires to its base level, we inevitably end up at a source of action that is external to our conscious self, i.e. something we do not choose. For example, I choose to eat this sandwich because I'm hungry. But why am I hungry? Because a lack of nutrients in my body has sent a chemical signal to my brain, triggering it to want to eat. Is my choice to eat this sandwich a free one, if it is ultimately caused by biochemical events outside of my control?
Why did u fall in love with that particular girl or boy u met at school for no reason. Did u actually choose ?? Or it just happened???

A similar analysis could be applied to any chain of action and desire a person could have. The answer is of course its a mix of both. There are certain things we have a choice over and there are other things which we have no control over.

The best advice would be let go of any expectations and try to enjoy the present moment
