You can follow the beaten path and call yourself an entrepreneur or you can blaze your own trail and really be one.
When Derek Sivers started CD Baby, he wasn’t planning on building a major business. He was a successful independent musician who just wanted to sell his CDs online. When no one would help him do it, he set out on his own and built an online store from scratch.
He started in 1998 by helping his friends sell their CDs. In 2000, he hired his first employee. Eight years later, he sold CD Baby for $22 million.
Sivers didn’t need a business plan, and neither do you. You don’t need to think big; in fact, it’s better if you don’t. Start with what you have, care about your customers more than yourself, and run your business like you don’t need the money.
Good read if you wanna start a business you like. There is not a single way to do business. You don't necessarily need to raise a huge funding.
On the contrary, you can start small and sustain your business step by step.
