Unicorns and time-space vortices might very well exist, but categorically effective topics for law school admissions essays unquestionably don't. That's because a topic's effectiveness necessarily varies with each applicant. Writing about a trip to Tanzania, for example, may revive one applicant's chances, but hobble another's. Thus, you must find the most effective essay topics for you. But how? Consider these defining attributes of exceptionally effective topics and your search is bound to be brief:

• It stirs you

Whether it's researching tree snails on Oahu or filling potholes in the Bronx, select a topic you feel strongly about and you're apt to project sincerity, an essential quality of outstanding law school admissions essays. And don't worry if you think your topic isn't inherently compelling. If it's of genuine interest to you, your prose will flow with an ease and intensity likely to impress any admissions committee. Conversely, pass on an "impressive" topic that doesn't excite you; lack of enthusiasm is a rot that weakens essays and admissions chances.

• It complements your pitch

Your pitch, no more than a couple of sentences, is the strongest argument for your acceptance to law school; it should permeate your application. "Tenacious, inquisitive woman who surmounted cultural barriers to become expert on Saudi Arabia is prepared to become Islamic law specialist"--that's the kind of pitch--concise, unique, impressive--which resonates with admissions officers. Whatever your pitch is, be sure to select essay topics that effectively highlight it.

• Personal details make it unique

You've selected an arresting topic that no other applicant can discuss--a space tourism flight out of Kazakhstan. Sounds promising, but an essay is likely to founder despite a fascinating topic if it lacks relevant personal details. That's the debilitating effect of abstract prose: it coats over what might be the distinctive hues of an essay like a drab hospital green. On the other hand, mundane topics, such as a walk to the newsstand, can be singular and riveting if animated by concrete personal details. So don't obsess over selecting a rare topic. Stud your essay with telling personal details and your topic will be unique.

• It focuses on your actions

Admissions committees are interested in your actions because they reveal your character, contextualize your accomplishments, and suggest what you'll achieve during and after law school. That's the reason selecting an essay topic which focuses on your actions instead of opinions is vital. So remember: no op-ed pieces--only when your essay is heavy on your actions and light on commentary have you found an effective topic.

• It fits law school into a logical progression

An effective essay topic positions law school as the logical next step of a progression, be it intellectual, professional, moral, or otherwise. That's good multitasking--impressing admissions officers with a reasoned decision to pursue law and accomplishments which promise success at it. It's also not that complicated and needn't be overt. How one coaxes hens into a backyard coop, for example, would be a clever topic to highlight the professional and personal development of a union negotiator primed for law school.
