It has been said before, but a good place to start is - raise the rears to get them to break free sooner. This isn’t always true, and depends on many factors, like tire brand, size, age, and car setup. At this point, since you are new, you should be experimenting with different things to see what you like. Oh, and pair up with someone that knows what they are doing, and pick their brain during the day.
