Basically, the reality is that you don’t COMPETE FOR AN LOA. So, there is nothing to do to obtain one. Imo, what people are trying to say, is to not worry about not getting one. If you put forth your best package, you may, or probably won’t, receive one. So, in the big picture, that’s why people say ‘don’t concern yourself with an LOA’.
A small percentage of each class receives an LOA. Not receiving one doesn’t mean you aren’t competitive. Receiving one doesn’t mean you are better than others. Not receiving one doesn’t mean you are a less desirable candidate.
IMO a better way of saying it, is to not assign a lot of self-worthiness to an LOA. Yes, it’s an endorsement of your application. But, it doesn’t mean you are a better/superior candidate than others. And it also doesn’t guarantee/ensure an appointment (all conditions must be met).
One of my own kiddos had one for about a week (until conditions were met). My other kiddo, a better candidate imo (from my perspective as a BGO - USNA), was placed on the waitlist. No LOA.
You don’t compete for one. It basically is an early appointment, if conditions are met. DO NOT RUSH an application in the hopes of obtaining an LOA. Dont worry one bit if you aren’t given one.
Good luck!
