Entering the legal profession

Is it too late for a 35 YOM to enter the legal profession? I’ve been delivering packages for the last six years and have had some job in transportation for the last twelve. I’m very good at what I do, I’m top ranked in most metrics my company cares about. But I’m frequently told I’m too smart for this job and I’m wasting my time. I do enjoy the work and the pay is *enough* to get by. But idk lately I’ve been wanting to do something more impactful. I’ve always been interested in labor law and the history of labor relations in the US. Maybe it’s just a phase, maybe it’s this Clarence Darrow biography I’m reading right now lol. Any responses or advice would be great!
