First I would like to ask why the interest in apologetics?
Honestly, it is mostly a selfish motivation. When I was in high school I just had a strong desire to learn, and apologetics was one of the things that piqued my interest. Now I have a pretty much insatiable desire to understand the Bible. My desire to study apologetics and philosophy isn't as strong, but it's up there. I just want to be able to defend the faith when I talk to family members who aren't saved, alongside knowing Christian truths of course and I hope that God will use that. Another reason is that logic and debate is interesting to me and I want to be a rock of truth amidst people who don't want to think their way through deciding their beliefs, but just pick and choose whatever feels good.
Now the second reason is because I want to know enough about the subject so that when my kids ask me how we can know Christianity is true, and can give them a solid answer. And I want it to be some part of our homeschool curriculum. There's a podcast by a Christian named Randall Niles who ever since he was twelve asked his parents questions about how we know there is a God, etc and they always said "well, you just have to have faith," and nothing more. He ended up becoming an atheist, and only after a several year search of the truth as an adult he ended up converting to Christianity. Now that has been in my mind ever since and I really don't want to make that mistake with my kids.

Oh, SolaSaint, if my avatar is worrying you about my grounding in the faith, don't let it. It's just a joke.
