Skateboarding?

im really frustrated about skating. ive been skating for almost 6 months and i practice almost everyday for at least 30 min. i really suck, but i really love skateboarding. all i can do is ollie consistently, land one foot on pop shuv it, and sometimes land a kickflip with one foot. i mean..ppl who skate for 6 months can do like a varial kickflip and stuff. i need some advice.
