Being Happy and Authentic

It sounds so basic but my question always comes back to how to be happy and authentic. I think I would be happier if I were more authentic—more the “real me” in all situations. I struggle between my professional/intellectual /working on my Ph.D. self and the me who wants to read romance novels, teach aerobics, and enjoy some Netflix. I think the real me is the latter, but I feel like I should/ought to also stay on my professional path as well….because I can, and it makes sense, and it’s more responsible. I’d love some advice on sorting this out. I know it’s a big topic. thank you!
