"It's like the process of growing up has made me less sure about me somehow" Jonathan Harris
Currently our lives are just extremely fragmented. Because of social media we've significantly lost our ability to 'live in the now'. Eckhart Tolle has an amazing book about this called "The Power of Now". I recommend you check it out.
Our lives are so fragmented, we are just living moment to moment. Do you care about tomorrow? Do you reflect on your past? Today is important. Glorious mistakes are very important. The present moment is very important.
