As a student in college, you can start earning yourself little amount of cash for your upkeep through your own efforts. Thinking over a business idea that will not eventually compromise your studies can pay you handsomely. This will not be an easy venture, but the advantages it may offer you is worth taking the step to pursue it.
If you are serious about your venture, assess your market, create a small business plan, and then source extra capital (whether it be through friends or family, crowd funding, or a bank loan) to make your idea a reality. There are actually university entrepreneurial loans you can access too.
