Your life has not been designed around you

Ephesianas 2:10 (emphasis mine)
For we are God's workmanship, created in Christ Jesus to do good works, which God prepared in advance for us to do.

that is what seems to be the very thing that's troubling you

I am not troubled by this.

I also believe that it is God's responsibility to make sure people go to the right place when they die.

Right, but in most of his interactions with men, he chooses to work through people. It's up to you whether you want to be one of those people or not. Bringing the good news is what practically the entire New Testament revolves around.

If free will is such a precious gift, what use is there for boyfishing, as if you can change it?

This sentence makes no sense. It's because of free will that people can choose where they spend eternity. So, how would the fact that there is free will make anything unchangeable?
