mi mismo/ yo mismo/ ellos mismos/ si mismos

Question

What is the difference between saying: 'mi mismo' and 'yo mismo' to say 'myself' 'ellos mismos' and 'si mismos' to say 'themselves' 'ti mismo' and 'tu mismo' to say yourself ?

Gracias

Answer 1

I've discovered something for you:

A ti mismo te corresponde actuar ahora. It concerns you yourself to act now.

Tu mismo eres quien debe decidir. You yourself are the one who should decide.

Tu mismo puedes hacerlo You yourself can do it.

A ti mismo te puede pasar It can also happen to you yourself. __

Answer 2

Both of these below mean the same thing:

Puedo hacerlo por mi mismo and Puedo hacerlo yo solo

Here 'mi mismo' means doing something alone.

yo mismo, I think is emphasising the fact that, 'I, myself have done something'.
