I always explain it comparing to watching a movie. Even when you start looking at the screen, the movie is already written and recorded. But that doesn't mean you know what will happen, and you will still feel something watching the movie. And you watch is because it's fun, it makes you think, you simply don't have anything better to do, etc.. As long as you personally feel your life has any meaning, your "actions being already decided" does not constitute any problem. What you feel in your life might be real, and in that case, rationally analyzing your life without taking those emotions into account is actually quite irrational and unfair. As another commenter says, you might be important for other people, make their lives better, and you can still feel and live all that. As long as you don't know where your decisions will lead you, them being "written" or not is irrelevant. If you have a defeatist perspective based on the results of your previous decisions, that's another thing, and it's likely your life will continue that way, but it's also possible you change over time (and the movie actually ends like that). Not due to free will, but still due to thinking, and reading, and caring about what other people —with as much free will as you, none— thinks and says.
