I second this. I am much younger than you (Early 30s) but very old looking for my age. People regularly guess that I'm 10 years older than I am. This has only worked to my advantage in the consulting space.

Companies want young naive employees who will work lots of unpaid overtime but when they hire consultants they want someone who's done the work before. There is a poise and sense of assurance that comes with age as well which you can definitely use to your advantage.
