Life is valuable because we exist. Everything that you've experienced, whether it's happiness or the lack of good moments, was available because you are alive. You have consciousness, and you can perceive yourself and the world that surrounds you.
I know that most of us would love to live in a blissful state of mind, feeling happiness and joy all of the time, but hardships in our lives are inevitable. It is desirable to learn from the difficult times so that we can learn to enjoy our lives in the present moment.
The quest for happiness might be different than we think, as happiness is a state of mind that occurs when we are deeply involved in our lives without searching for it. Happiness might not be so much about us but about our ability to live a meaningful life and find a purpose that is outside our own being.
I invite you to reflect on these deep ideas, and I hope that you'll be inspired to change small things in your life that will bring more joy and accept the difficult times, as they have the ability to teach us many profound things.
