Free will may not be all it’s cracked up to be. Free will gives us the freedom to do not only good things but unhealthy things like self-destructive behavior. You may say I can do what I want because I have the free will to do so – so I will.
On the other hand you have the freedom to say I won’t – this just may be the freedom you are looking for.
I won’t take what does not belong to me. I won’t talk to the pretty co-worker but go home and talk to my partner. I won’t take that hit of coke or pop that pill or take that drink. I won’t engage in unhealthy behaviors. I have the freedom to choose either way. But “I won’t” just may free you up to enjoy a fuller life.
