Is 37 too old to start a new career?

Thirty-seven is not too old to start a new career, especially in fields like AI consulting where experience and judgement are valuable. By that age you usually understand how businesses actually run, have networks in one or more sectors, and know how to manage yourself under pressure. Switching career tracks does require humility and focused upskilling, but clients often prefer someone who has seen real operational challenges over a very young specialist. If you can articulate a clear niche, build visible proof of skill (case studies, prototypes, small wins) and show energy plus reliability, your age can be a selling point rather than an obstacle.
