Every single manual transmission is different. You just need to drive the car more to get the feel of it. European cars are kind of known for a more "stiff" manual transmission, but you can do it! Just pay a little more attention to what gets the car moving best (i.e. more gas, more feathering of the clutch, gradual gas and clutch, whatever) If you take the time to really figure out that "friction point" where the clutch starts to grab, you'll figure it out in no time. Remember, you don't just keep releasing the clutch all the way through, you have to "float" at the friction point to allow it to really grab while you give it gas.
Once you figure out your transmission, driving a manual is a blast:-) Good on your dad for starting you with a manual, because now there is nothing on the road that you couldn't drive in an emergency or whatever. Good stuff!
Keep it up, don't get frustrated, you can do it!
