What are some good tricks to learn 5 months into skateboarding?

You need to start working on your flip tricks. I would start with a heelflip, it is much easier that a kickflip. I have been skating for ten years and kickflips will still give me trouble some days. You need to learn flip tricks for the simple reason that EVERY skateboarding trick besides most grinds, grabs, and flatland require you to know how to kickflip and heelflip.
