Self-employment means most of the time you have to do the job

[Silverobama]

The following conversation was between my friend and I. He was interesting in the job (tutor) I'm doing right.

David: You've been working as a tutor for so many years, right?
Silver: Yes. Since you left for the UK.
David: Wow, good for you. What are the differences of working as a tutor and a school teacher?
Silver: I don't know what it's like teaching at school. But working as a tutoring is totally different. Tutors like me and some of my friends are mostly self-employed. Self-employment means most of the time you have to do the job on your own.
David: That's interesting. Could you explain that in more depth?
Silver: Sure. I look for tutoring jobs myself and I need to tutor the students myself. I also have to cope with demanding parents myself. In a word, I do all sorts of things myself* because I'm self-employed.

*: Well, I've been reading posts about the difference between "by myself" and "myself" and I think they're both fine in this context.

Is the italic sentence natural? If so, please suggest just one alternative.

It's "working as a tutor". (I've got to go.)

Being self-employed means that most of the time you have to do things on your own.

Note my changes above. Your first and third "myself" were OK but, as you can see, I'd use "by myself" for the second. I think you're starting to get the hang of it, though.
Is your friend David a journalist or similar? I wouldn't normally expect a friend to say something as formal as "Could you explain that in more depth?"

He's a friend of mine but he speaks very formal English because he has been living and working in the UK for seven years!

I know the normal expressions among friends are "Tell me more!" Am I right?

Much appreciated!

That doesn't explain why he speaks "very formal" English. I would say that's just his speech pattern for whatever reason.

Say: "I know the normal expression between friends is 'Tell me more!' Am I right?"

Also possible:

I'd like to hear more.
That's interesting.
Go on, please!
Interesting.
Do you have any more to say about that?
