Your speed increases relative to what?

You are always at rest relative to yourself. Your mass doesn't increase
from your own perspective, no matter what something else measures your
speed to be. (From your own perspective it's that external observer's
mass that's increasing, not yours.)

Here's an easier question: How fast would you need to travel (from
the point of view of Earth) in order to reach that star in 10 years
from your own point of view?

That is a valid way of looking at it.

You feel not the force of acceleration but the force of the rest of the
universe's mass increasing.

Which reminded me of a story by Harry Harrison* called Toy shop.
http://www.gutenberg.org/ebooks/22966


similar. Some hobbyist in the depth of England, it could have been Norfolk or
the West Country. Invented a gizmo in his garden shed which did something
similar. Only he immigrated to Oz where someone sponsored him to research it.
Never heard about him again. Spooky!

I thought that it was an Isaac Asimov short story. But I came across it today
and it is only a couple of pages.

It has stuck with me for about 50 years.
I don't know whether it was my age or if there were a lot more "make you 
think" short stories. It was like a sub-sub-genre with points for 
brevity. You have probably read Knock. The shortest SF story. If not:

Somehow, now that you mention it, this sub-sub-genre seems to have 
totally vanished from the shelves. A pity; it was most enjoyable.

Which reminds me of the following story by Damon Knight: "To Serve Man"
http://perrylocal.org/mostova/files/2011/09/To-Serve-Man.pdf
Like you, it stuck with me since the 1960's. I first read it in French 
translation, in the now legendary magazine /Planète/.

Isaac Asimov had a weakness for Short-short stories that were puns.

That one is one of my memories too.
I did not read many magazines by the time the American ones got to 
Glasgow they would be in batches several months late. The British 
magazines would be difficult to find. It was mostly library books that 
kept me going.

I really got started on SF when I moved to Amsterdam in '66 where I 
discovered Analog and began collecting SF books. Iirc Analog was the 
only magazine available in stores; others (no UK) were either not there 
or only irregularly.

I was about ten when I found Kemlo the space cadet. I have been hooked 
ever since. Glasgow being a port, would get pallets of American Pulp 
Fiction that had been used as ballast. They were sold in "Second hand 
bookshops" where you could return them and get back half of what you 
paid. They were really subscription libraries for American genre 
fiction. Cowboy, WWII stories, Romantic and SF. These shops were always 
in poor parts of town, near either a railway station or the docks.
