It was interesting to read your story.

There are people who can use this text editor well enough to write on the right of this picture. I'm not one of them

Well, it seems not to be essential to be successful on Steemit ... :-)

But in case you are interested, one possibility is to make a html table:

[table]
[tr]
[td]

[/td]
[td]
blablablablablabla
[/td]
[/tr]
[/table]

From [tr] to [/tr] is one row and between [td] and [/td] is one column. If you replace all '[' and ']' with '<' and '>' it looks as you see bleow:

blablablablablabla
