The best advice I can give is practice. Acquaint yourself with the friction point so you don’t need the parking brake to help you start on hills. The same trick can be used for reversing, but it is a little trickier since you’re backing up. I have never had to re-learn to drive a manual since the longest I have gone without driving one is about a year, plus I have always been a car enthusiast, so it was practically second nature when I learned it at age 15. You’ve only had the car for two weeks. Give yourself some time to get used to it again, but be sure not to ride the clutch out of fear of stalling or bucking the car. The car couldn’t care less if you stall or buck it, but the clutch won’t forgive you if you ride it and smoke it.
