Freedom can be burdensome. That is after all the basis behind totalitarian politics. Left free, most people run amok. They indulge in self-destructive or at least unproductive things. They need minders... the police state, the authorities, the routine of workplace cubicle and punch-clock and boss.... I love having that freedom. Feeling that one needs to "accomplish" something is just an idea. Who says? The truth is it's just not that deep, and it usually ends up just being another ego thing. At the same time, setting and accomplishing goals is great and can add texture and meaning to life.
One hopes that as we age-out of employment, whether via FIRE or other cadence, we also mature, becoming self-energized, to the point where not merely our free-time but our free-volition becomes filled personally, without external encumbrance, remonstrance or fiat. Where I think that so many of us go wrong, is that we become financially independent long before we arrive at volitional independence. The former frees us to retire, the latter fetters us self-limiting circles of ennui and anomie.
