So now to come to the real question of punctuation:
periods

commas

colons

semi-colons

and capitals

and small letters

I have had a long and complicated life with all these.

Let us begin with these I use the least first

and these are colons and semi-colons,

one might add to these commas.

When I first began writing,

I felt that writing should go on,

I still do feel that it should go on but when I first began writing I was completely possessed by the necessity that writing should go on and on and if writing should go on what had colons and commas to do with it, what had periods to do with it what had small letters and capitals to do with it to do with writing going on which was at that time the most profound need I had in connection with writing.

What had colons and semi-colons to do with it what had commas to do with it what had periods to do with it.
