Being true to yourself is a lifetime project. It can't be done all at once but slowly. Just as life doesn't come with an instructor's manual, neither does how we treat ourselves and others. We tend to make it up as we go, and there is nothing wrong with that. That's how we learn about ourselves. However, to live an authentic life, we must be true to yourselves and please delete the last sentence of the first paragraph as it is now.
How we create our life is a work of art. Each day, we have a chance to create it anew by choosing to do certain things and not others, by surrounding ourselves with wholesome people and things we love. We get a chance to adopt a philosophy, appreciate insightful books, and engage with the world in an authentic manner. We are the artist of our experience in the world. We decide how to perceive things and how to understand it based on who we genuinely are.
Further, each of us is unique. We should live our lives as only we can by autonomously developing who we are and becoming aware of what your authentic stamp on the world will be. There is no other person like you. So, be sure to celebrate who you are every day.
