Don't be, filling a pen from a bottle is a piece of cake, especially with a converter. If you're nervous, put some newspaper down on your table-- you probably won't drip, but you'll feel better. Have a paper towel or two to clean off your nib after you're done filling, and you'll be all good. Getting a good fill in a converter is easy, because you can actually see the ink go in (with old-school lever-fill pens, you sort of have to guess as to when the pen is full). From the time you open your bottle of ink to the time you're writing happily away is less than a minute.
