As I've got older I've realised increasingly how much I need alone time. It's not that I don't like people or that I don't ever need company but I need - really need - to have some time each day to myself. To be alone with my thoughts or even to just be alone, not thinking.
I have always been an extremely shy person - although I am getting better with that - so I think some of my need for aloneness stems from that. Added to the shyness, I am an only child so my earliest memories are of making my own fun rather than relying on the input of others. Whatever the cause may be, now I find that even an hour or two of quiet solitude is just the ticket for calming any feelings of anxiety or angst I might be experiencing or for just getting myself back into my own rhythm, rather than jogging haphazardly along to the rhythm of others.
Apparently one can be diagnosed now as a 'highly sensitive person' and I think I am perhaps leaning in that direction - dislike of crowds, aversion to loud noises and bright lights, need for peace and solitude. I also know it's important though to balance that need with regular interaction with the rest of the world lest one goes a little hermity and weird. I do think it's good to be able to recognise and respond to one's feelings, though.
Are you a 'loner' like me or do you love to be surrounded by people 24/7?
