A stupid phrase that is used, commonly on Instagram, to give the false reality that you can wake up and choose which "life" you want to live. Perhaps you want to be a lazy dog, or a human facing the challenge of whether to have avocado on toast or a green smoothie for breakfast. Either way, it's got to be the best (breakfast) life you could possibly be living.

Usually people have specific conditions under which they would like to live, and have specific goals they want to achieve for that to happen. For example, losing weight, getting fit, being debt-free, having a good romantic relationship, being a home owner, being able to travel whenever they want without being tied to a regular job. Any of those would probably be among the list of things that make an "ideal life" for most people. "Living your best life" means living under the conditions you consider to be ideal for you, or that you're at least satisfied with your progress towards meeting said conditions. It does not imply that anyone living their best life is free of stress or any emotional turmoil in their life, since that's a part of everybody's life regardless of the living conditions one is under.

To assimilate what a previous definition said, basically the phrase 'Living My Best Life' denotes a lifestyle (or a moment in time) where an individual is in its most optimal state of being. This state is completely subjective and varies from person to person. To some folks, living their best life may imply breaking free of some restraint. To other folks, living their best life may imply getting out of an unhealthy state and into a more healthy state. And to some other folks, this phrase may simply just mean getting by the day doing what they love.

Whatever the case may be, in all cases, 'Living My Best Life' emphasizes that only 𝗬𝗢𝗨 are in control of your life and only 𝗬𝗢𝗨 can understand what is best for you, regardless what other people may think or expect of you.

TL;DR Living My Best Life = living life under your own terms, at your own pace, with your own ideals and expectations.
"My friend is a music producer. He had big ambitions, however, living with his parents restricted his creative freedom. Thus, he set off on his own and moved into the big city (e.g. Toronto, NYC, LA). He lived in a small crappy apartment in a shady neighborhood, and survived off with hardly any income to pay his rent. Despite all that, he said he was living his best life."

"After a grave talk with my mother, I came to terms that my degen sleep schedule was causing distress to my life. After taking considerable effort to correct it, I now end up sleeping at 4am and waking up at 11am instead of my usual 9am-5pm degen hours. Even though I could not meet the normal 12am-7am standard set by my mother, I was already beyond satisfied with the result, and I felt like I was living my best life, and that is what ultimately matters to me."

Circa 2020: Prior to the Pandemic of COVID-19, arrogant young people born in what were called the millennial or gen z generations held this belief they were invincible and could not be prevented from living the life they imagined, and a virus was not going to stop them. Unfortunately for them, it was a great awakening.

No one really knows, since “best life” is such a broad term. Generally used when having fun or relaxing. Makes depressed people cry because they are also living their best life and it sucks.
