Early on, having an entrepreneurial mindset will allow you to be more strategic about things such as how you use your time, where you spend your money, and the kinds of connections you build. While the responsibility of running and developing your rapping business will largely be up to your manager and other team members (more on that later), it is still up to you to drive your own career.
If you struggle with thinking this way, don't worry. Mindsets can be developed over time, and there are plenty of helpful resources that don't cost much. For example, you can talk to friends or family members that own businesses and ask them how they got started. Such information is priceless, even if they are not in the music industry.
