New to waxing! (Did it myself)

So normally I just shave. But last time I've tried waxing my legs at home, and after a few times I camt seem to pull it off fast enough because it hurts.

If someone else pulled it off, I think it would get all the hair. When I do it myself I pull it off slower every time and it doesn't get all the hair.

So anyone have any waxing tips for me? And what kinda of wax do u use? I've tried the sugar wax and the waxing strips.

Also I'm only waxing my legs right now... I dont think I could wax my armpits or bikini area.
