Starting a business can be approached in different ways. Kevin Systrom, the founder of Instagram, started by wanting to work on his own stuff and not have a boss. Blake Mycoskie, the founder of TOMS, started his first company out of necessity by solving a problem he faced. Scott Galloway, a professor and entrepreneur, emphasizes that entrepreneurship is not just for those who are bad at working in an office, but for those who are risk-aggressive and willing to do uncomfortable things. It's important to get the easy stuff right and seek to solve a problem in the world. Nowadays, there are many resources available to help start a business, such as incubators and funding opportunities.
