I don't think you're going to find many people who are living it real who are head over heels in joy and contentment.
There's a lot wrong with our world and you can find hints to this reflected in the lyrics of pop songs: "There's a city in my mind" ~ Talking Heads.
We all have a notion as to how we would idealistically like life to work for us but once people get to about your age they begin losing their rose tints and realize those child hood stories are only motivational demonstrations for young and developing minds.
In reality we instad have economic crisis, poverty, wars, mental illness and even though we never came in direct contact with those issues previously - The people we interact with, on a daily basis, are rippling the hurting and suffering from those major realities.
This results in broken friendships, romances, employment, etc.
The mass majority of the world is just not psychologically or emotionally strong enough to manage the discord we face in this existence.
Your one saving grace will be when you realize how broken everyone is and stop taking this all seriously. Then deciding to make the best of things by using the entropy to strengthen your own heart and psyche.
A lot of people beat themselves up because they believe they are not 'what it takes' to succeed but in all honesty it isn't just you - Most people are not functional enough to make cohabitation in our current society work.
Our current government templates need to be revised with support and fellowship as its main focus but as Broken Minds will also establish Broken Rule - Our world, instead, focuses on animalistic survival tactics of using each other like rungs in a ladder to climb higher.
You can't kiss your sweetheart with your shoe standing on his/her lips.
