I have also driven manuals all my life until 2 years ago when I made a switch to an automatic. But now I am back with a manual again. IMO, its easier to switch from manual to an automatic/dsg than a person who is used to automatics and then wishes to switch to manual.
So Rolfe, do not worry, it will be convenient and effortless. You will also suddenly find yourself with more time to think and ponder life's questions while driving...
