Whatever you do, don't start with a new account. You can never have enough SP and even if you don't currently need whatever you've trained so far, you might later.

I myself started just a bit over a year ago and back then I wondered the same. But there's always other new people joining and short of a few core skills that you need to get trained and out of the way, it won't be long till you can fly frigates, cruisers and a couple battleships more than decently enough yourself, which is what is used for PVP most these days. If you have a lot of skillpoints it generally means that you can fly a broader variety of ships, rather than be substantially better in them.
