Who is harder on oneself' than yourself?

I know that whenever I'm not efficient enough at work or wherever... I start telling myself off.

And then, there is another self of mine who starts telling the other myself to shut up and stop being so harsh.

At the end of the day how many selves are there in here?

In the past I thought it was just me, but it appears as though there's a whole.... Raz breed!

And living with all of them is as exciting and as weird as it can be;-)
