It's a herculean feat to overcome the death of a loved one. In fact, most people never really "move on" from grief, but rather adapt their lives by moving forward to honor that person's legacy by going after their personal dreams and living the happiest life that they can.

She has also posted several tributes to her late brother, and says that her online profile was intentionally selected as such because she wants his "name to live on."

Herbo's.Ari has reportedly earned a hefty amount of wealth for herself as per approximate reports online: It's said that the model has anywhere from $1 million to $5 million in combined assets and liquidity at her disposal.

Not too shabby. \n\nIt appears that Kyle's sister is well on her way to building an empire, honoring her brother's legacy through it all.
