I think that meditation has really helped him and Meghan also deal with the non-stop press and noise.
Yes, Meghan has been practicing yoga from the age of 7, and meditation for years as well. Meghan learned yoga from her mother, Doria, who apparently was all about self-improvement and new-age, free-spirited thinking from a young age herself.
Despite all the petty slamming in the media (which surely hurts Meghan on some level), she really seems chill in public. Her acting training has definitely come in handy as a member of the royal family! She knows how to shine for the cameras, and how to keep her nerves under control. I think Meghan experienced considerable nerves in the beginning, especially for her first Christmas at Sandringham. But now, Meghan looked very self-assured and cool as a cucumber last month for Christmas with the royals.
And the acting skill is not about pretense either, it's about knowing how to carry oneself with control and grace. Meghan's and Harry's caring emotions are clearly genuine and heartfelt. I also think that Meghan has learned how to stay fully in the moment, which is definitely a life skill, which she's surely passed on to Harry too. Although, I think Harry has been good at that already in the way he's very present for and attentive to the people he meets.
It was so sweet of Meghan to give the young girl in Birkenhead a single rose from the bouquet, as the little girl seemed to be crying after having to give up the flowers.
