Slack advises those considering a side hustle to start with something aligned with their interests or skills. “Set aside a few hours a week, whether it’s dog walking, reselling thrift store finds, or creating content online—just get started. Success comes from tapping into existing opportunities rather than reinventing the wheel.”
