The same way about a degree. If you want that job bad enough, you just have to do some of those things. Volunteering is not a bad thing and can actually be rewarding. Find something you enjoy doing and just do it. Elementary schools and special needs for adults are a couple of places I've volunteered at. They love to see us come out to talk to them about flying. Wear your monkey costume and just take some time to tell them what it is you do. You will be surprised some of the questions they ask. Some are downright hilarious, but some will blow you away and make you actually think about it before you answer!!!
