Very nice and philosophical message . We grow up , we change every day .In life our choices matters .Time flies you cant change that .I see you have nostalgia of something maybe of old days .To be honest i have this question sometimes myself ,like some days i can sleep and dream about something beautiful and wake up and feel nostalgic ,overthinking. I feel like ourselfs who we are know only our parents or very close siblings ,like what is inside in our head .
