Eagle Scout Requirement 6: Attach to this application a statement of your ambitions and life purpose and a listing of positions held in your religious institution, school, camp, community, or other organizations during which you demonstrated leadership skills. Include honors and awards received during this service. Take part in a Scoutmaster conference with your unit leader.
Let's look at this single requirement in the two parts it really is. First, your statement. This is very straight forward, and an excellent opportunity for you to tell members of your board of review what you do outside Scouting. The statement will reveal who you have become in several ways. Scouts who have been successful in Scouting will find it has spread to other areas of their life. This is especially true of Eagle candidates, since you have actually developed character which demonstrates the Scout Oath and Law in everything you do.
Don't be shy about bragging! List it all! Most Scouts don't consider this well enough to remember all the things they do. And it is key to something that will help you all your life - that being establishing a good self-esteem, which, by the way, is to do good things and remember what you did!
List all the various awards and honors you've achieved along the way. These may be a medal, plaque, or certificate, but could also be a different type of honor. For example, a letter from a principal or volunteer organization recognizing your contributions. Or maybe a letter from an elected official thanking you for being their assistant (like a Page) for a season. Maybe it's a newspaper article mentioning you. If it made you feel honored, it counts!
Next is the Scoutmaster conference. You've been through this drill before, but here, of course, it is more significant. You are applying for the highest honor available from the Boy Scouts of America. Walk the walk, talk the talk. You should be prepared beyond your unit leader's expectations.
Make sure you have completed all the requirements and have everything ready for him or her to review. You might want to talk to him/her ahead of time to see what is expected in the way of documentation when you have the conference (such as, are you expected to have everything completely written and ready to turn in). Remember, this conference must occur prior to your 18th birthday.
