To ask for the deeper meaning of something, is to ask for that which makes something possible. I will provide you with an example:
If one understands the meaning of a kiss, one understands the kiss as a kiss in terms of its purpose: to demonstrate affection.
So affection is not only the meaning of a kiss, it is what makes a kiss possible.
When I say that the meaning of the future is a projection of possibilities, I am saying that possibilities make the future possible.
Free will presupposes an awareness of possibilities, because in order for you to have choices, you must first have an awareness of them.
So if you are not aware of your own possibilities, which is what the future means, then you are not free and are enslaved by what is "actual" (meaningless).
And if you go through life not trying to find meaning in everything, then naturally, you will not lead a meaningful life.
