Money just usually isn't one of them.
While most celebrities may not be able to understand money woes, there's a group of celebrities who can relate to parents like us--they, too, have children with special needs.
Sadly, in a world where special needs are perceived as a negative thing, many celebrities feel compelled to shield their children from the public eye.
Personally, I completely understand with celebrity parents want to shield their children from public scrutiny, but I also admire those who have shared their child's stories and became advocates for their child and others with special needs.
Here's a look at some of them:
When Colin's son, James was four years old, he spoke out about James' condition, Angelman's syndrome, a genetic disorder resulting in severe developmental delays, speech impairment, seizures and problems with balance. Colin has been quoted as saying this about his then-four year old son: "The only time I'm reminded that there is something different about him -- that he has some deviation of what is perceived to be normal -- is when I see him with other four-year-olds."
"Then I go 'oh yeah' and it comes back to me. But from day one I felt that he's the way he's meant to be."
(Note: this quote really got to me when I read it because I feel the same way about my son. It's so easy to forget Coop is different until he's around other kids because his normal is our normal and we love that he's unique.)
Royal Pains' Mark Feuerstein opened up a few years ago about his daughter Addie's battle with a rare congenital heart defect known as ALCAPA, or anomalous left coronary from the pulmonary artery.

Toni has been candid about her struggle to accept that there was nothing she could have done to prevent son Diesel's autism.
She told MORE magazine, "Complete blame. I thought it was because of something I did during my prenatal care".
"I started thinking, was it because I didn't take my vitamins every day?"
"It took a few friends to make me realize that there was nothing I could have done to prevent this."
Backstreet Boys frontman Brian Littrell and his wife shared their son's story with People magazine in 2009.
In the article, the Littrells share about their seemingly endless battle to correctly diagnose their son Baylee's condition, which was finally correctly diagnosed as Kawasaki's Disease.
Said Littrell in the article, "Never give up. Doctors are not always right, but they are there to help. Be an advocate for your child."
The Daily Show host opened up about his son's battle with Celiac Disease, a condition in which damage to the small intestines blocks absorption of nutrients.
It's very painful but can be treated by following a strict, gluten-free diet.
