Wow, i think i started gogin out on my own a lot younger than 12 but i guess its differant strokes for differant brushes,
Good luck in gogin out be careful of those grid holes and the high curbs and you should be fine,
Remember if your worried about getting lost you can leave a trail of breadcrumbs from your door so you can find your way back properly
Unless you was meaning your starting up your own business in which case good luck,
