Alone is state of being or body, whereas loneliness is state of mind.
Celebrating your time alone
I have many Sundays when I do not have a conversations with more than 5 people face to face. A conversation is something meaningful and more than just exchange of instructions or tasks. Many a times, I only have conversations virtually, i.e. not face to face.
In the last 2 years, I have learnt to celebrate my time alone. It is liberating and empowering - calms you down and you can get a lot done with focus.
Today, I ended up spending my time with 2 km swimming, catching up on sleep, reading a book cover to cover, 10k steps and listening to an audio book.
