Solitude and the Mr & Mrs TV show
My first significant message that I placed in my literature, was "Embrace your aloneness." You should do so before entering the "world". Ultimately, we all have to, at least to a degree.
We might think we know people well, but when they're thrown into sudden situations, requiring snap decisions, people may surprise us. Life was perhaps mirrored by the old Mr & Mrs TV show that started in the 1970s, when sometimes, after several decades of marriage husbands surprised wives, and wives surprised husbands, with their answers.
Realising our own aloneness well before our peers do, can create a real challenge, and it may lead to loneliness, but that's not the way to view it. There's a negative ring to that. Instead, it's about solitude, and solitude has been the driving force of much of the world's great creativity.
So positively embrace your aloneness, and Godspeed in your endeavours.
I Googled for a page of relevant quotes, and found this great hit.
