At age 23, Tina Fey was working at a YMCA. At age 23, Oprah was fired from her first reporting job. At age 24, Stephen King was working as a janitor and living in a trailer.
At age 27, Vincent Van Gogh failed as a missionary and decided to go to art school. At age 28, J.K. Rowling was a suicidal single parent living on welfare.
At age 28, Wayne Coyne ( from The Flaming Lips) was a fry cook. At age 30, Harrison Ford was a carpenter. At age 30, Martha Stewart was a stockbroker. At age 37, Ang Lee was a stay-at-home-dad working odd jobs. Julia Child released her first cookbook at age 39, and got her own cooking show at age 51. Vera Wang failed to make the Olympic figure skating team, didn’t get the Editor-in-Chief position at Vogue, and designed her first dress at age 40. Stan Lee didn’t release his first big comic book until he was 40. Alan Rickman gave up his graphic design career to pursue acting at age 42. Samuel L. Jackson didn’t get his first movie role until he was 46.
Morgan Freeman landed his first movie role at age 52. Kathryn Bigelow only reached international success when she made The Hurt Locker at age 57. Grandma Moses didn’t begin her painting career until age 76. Louise Bourgeois didn’t become a famous artist until she was 78. Whatever your dream is, it is not too late to achieve it. You aren’t a failure because you haven’t found fame and fortune by the age of 21. Hell, it’s okay if you don’t even know what your dream is yet. Even if you’re flipping burgers, waiting tables or answering phones today, you never know where you’ll end up tomorrow. Never tell yourself you’re too old to make it.
Never tell yourself you missed your chance.
Never tell yourself that you aren’t good enough.
You can do it. Whatever it is.

Researchers Discover Key Link Between Mitochondria and Cocaine Addiction
For years, scientists have known that mitochondria—the power source of cells—play a role in brain disorders such as depression, bipolar disorder, anxiety and stress responses. But recently scientists at the University of Maryland School of Medicine (UMSOM) have identified significant mitochondrial changes in brain cells that take place in cocaine addiction, and they have been able to block them.
In mice exposed repeatedly to cocaine, UMSOM researchers were able to identify an increase in a molecule that plays a role in mitochondria division (or fission) in a reward region of the brain. Researchers were able to block this change by using a special chemical, Mdivi-1. The researchers also blocked responses to cocaine by genetically manipulating the fission molecule within the mitochondria of brain cells, according to research published in Neuron.
“We are actually showing a new role for mitochondria in cocaine-induced behavior, and it’s important for us to further investigate that role,” said Mary Kay Lobo, PhD, Associate Professor of Anatomy and Neurobiology.
The researchers initially studied the mitochondria in cocaine-exposed mice and determined that mitochondria fission increased in the major reward region of the brain. To confirm this same change in humans, researchers were able to identify similar changes in the mitochondrial fission molecule in tissue collected from post mortem individuals who were cocaine dependents.
Dr. Lobo said that this latest research could help UMSOM researchers better understand changes in brain cells and mitochondria from other addictive disorders. “We are interested to see if there are mitochondrial changes when animals are taking opiates. That is definitely a future direction for the lab,” she said.
