It all begins with an idea. Maybe you want to launch a business. Maybe you want to turn a hobby into something more. Or maybe you have a creative project to share with the world. Whatever it is, the way you tell your story online can make all the difference.


Handle all firearms as if they were loaded! Never forget that a gun has the potential to produce serious injury or death in a single instant of carelessness. Make safe gun handling a habit to be followed at all times. After you determine that a gun is unloaded, continue to handle it as though it were loaded. 

Always keep your firearm pointed in a safe direction! In selecting a safe direction, you must also take into consideration that a bullet can ricochet or glance off any object it strikes, and that bullets can penetrate walls, ceilings, floors, and windows. 

Keep your finger out of the gun’s trigger guard and off the trigger until you have aligned the gun’s sights on a safe target and you have made the decision to fire! By keeping your finger completely outside the trigger guard until you have aimed at the target, you guarantee that any shots you fire will go safely in the direction of your intended target.

Always be certain that your target and the surrounding area are safe before firing! Remember that a bullet can travel as much as several miles, so you should be certain of what your bullet could strike before you pull the trigger. Never fire at a movement, a noise, a flash of color, or a rustling bush without positively identifying your target.
