Countless earnest people put a lot of time and effort into finding meaning in life but don't actually experience it because they look to outside sources rather than looking inside themselves. A major element of self-awareness is developing the ability to understand yourself so well that the meaning of life becomes clear to you because you're living from the core of your being.
When you're looking for meaning, it's important to examine the inner workings of your mind and heart, where the answers reside. Take the time to find out who you genuinely are and what you really want to do in life and you'll become more fulfilled from the inside out. For example: I found great significance when I finally decided to be a poet because I knew it reflected the authentic me. Now I live each day full of joy and purpose.
You can spend a lifetime looking outside yourself for happiness but it won't be as satisfying as simply following your true path. As you increase your self-awareness, you'll find that the answers you've been looking for will reveal themselves. How do find meaning in life?
