How to prevent acne?

I'm a 14 year old girl (healthy, 5'2 and 100 pounds) and I have no acne whatsoever, and yes I've already gone through puberty. It started when I was 12. My face is baby smooth, I have gotten pimples on my face but only one at a time and that's every few months. In my family, no one has acne. All my siblings are done with their teenaged years except for one, and he's almost 18. None of my siblings have or had major acne, they had it like me...one pimple every few months. My parents never had acne. My cousins/uncles/aunts/etc don't have it either. I know I won't get breakouts, but how can I prevent any from happening just in case? I drink plenty of water. I eat pretty decent, I go out to restaurant quite often but I always have a few healthy stuff during the day, like peas, salads, apples, etc. I shower nothing less than 2-3 times a day and use a face wash everytime I'm in the shower. I also never touch my face and my hands are never dirty because I wash them. I don't have oily skin either. Do you think I'll be okay? Thanks :)
