Keep guard against hypnotic fortune

Fortune doesn't have the long reach we suppose, she can only lay siege to those who hold her tight. So, let's step back from her as much as possible." Seneca

I don't think that Seneca is telling us to step away from fortune, as in whatever you do, don't succeed. He is warning us that if our only goal is to get as close as possible to her and by all means necessary, we will lose our good soul.
