You can run online businesses, whether selling products or services, and your website can look just as professional as a business with a physical storefront.
The Internet has also been a boon to telecommuting and remote workers. You can save money on commuting costs, buying lunch and your Starbucks beverages, wardrobe, automobile maintenance, etc. You can avoid the stress of driving to and from work in rush hour traffic and you can free up a significant extra chunk of time that you'd otherwise spend getting to and from work.
