Proximity Alert
Q: Why do people you love hurt you?
A: Ah, the classic conundrum!
Let me answer your question with another question, dear reader: Who else is going to hurt you -- people you hate?
I'm assuming here that you're relatively normal and don't go out of your way to surround yourself with people whom you utterly despise? Are you making the age-old mistake of hanging out with pedophiles, necrophiliacs or perhaps Veronica?
If so, that's gonna be a problem, because those dudes will most likely rape you -- regardless of age, gender or pulse.
If that's not the case, then who else has access? You guessed it, the people you love!
So it's generally a matter of proximity.
It's probably true that your enemies would like nothing more than to punch you in the throat and push you into a pile of garbage while you're gagging for air. But if you don't let them close to you, collapsing your windpipe with a swift karate punch is simply not an option.
Honestly, the easiest way to not get hurt is to be cool like Fonzie (and myself) and not care about anything.

Eeeeeeh!
PS: I would be remiss in my duty if I didn't also mention the possibility that the people you love do, indeed, hate you. Perhaps they are the types that subscribe to "keep your enemies close"?
I wouldn't advise you to get paranoid, but it's entirely possible that they are all out to get you. Perhaps they even have secret meetings about how to best make your life utter hell while you're out experimenting on your cats, or watching torture porn. You just never know for sure.
KEEP ALL YOUR EYES OPEN!

You may find people wanting to repeatedly dip your head in the toilet. Not to worry, this is perfectly natural when you use phrases that don't exist in an attempt to get popular. You just need to have faith that after a few good flushings, you'll win them over.
3) Invent time travel or teleportation. It may sound like science fiction, but this is an area of research that the human race is really slacking off in. Sure, I've been dabbling myself, and have actually been able to transport my hand across the room 20 metres, only to get it stuck in a cement wall and spend hours with a hammer and chisel trying to free it so I could sew it back on. But, even though I can definitely do it alone, it would be slightly faster if we also had the world's greatest minds to support my efforts.

Population control: war tends to wipe out a lot of people, and since a large percentage of our current population is essentially useless, chances are we'll cull quite a lot of those.
Doctor. Admittedly, this is a little off-the-shelf, but you can't deny that Jesus' ability to heal any disease or ailment would come in very handy in the medical profession. However, job satisfaction would be an issue, as healing isn't particularly challenging for Jesus, and of course getting an appointment would be a nightmare. He would drive pretty much all other doctors out of business, too, which may lead to another unfortunate and bloody crucifixion.
