Josh Brolin marks 8 years of sobriety in poignant Instagram post

Josh Brolin marked eight years of sobriety with a lengthy Instagram post that ended with him thanking God as well as his friends and family for "the most punk rock sobriety imaginable."

"Sobriety is finally loving without every thought being about how it affects only you. Sobriety is a moment of being able to love and be consumed by the glee it brings someone else. Sobriety is knowing the difference between selfishness and integrity," the "Dune" star began.

"Sobriety is knowing that God is in everything and that it is made up of every color (and mixture of color) that exists," Brolin, 53, added. "Sobriety is knowing the moon late at night when she was there for you in your toughest hour and, now, again, her witnessing your greatest joys."

He went on to list the joys of being sober, including getting "a card from your wife telling you how grateful she is for you having made the decision to put it down and to live" and how "your children look at you and trust what they see."

"Sobriety is about living better than your remembrance of what your greatest drunk ever was — an everyday malleability into gratitude for what is," Brolin continued. "None of this is deserved. All of it is perception."

The actor, known for playing Thanos in the Marvel Cinematic Universe, has been married to wife Kathryn since 2016 and is the father of four, including two children shared with ex-wife Alice Adair.
