You can find leadership opportunities within every activity you decide to pursue. Whether you're the captain of your basketball team or lead a community outreach program, the opportunities are endless. Even if your role isn't in a typical leadership role, there are always ways to demonstrate your leadership skills.
For example, if you're volunteering at a homeless shelter, perhaps you could instigate starting a monthly community clothing drive. If you're working as a lab assistant in a research facility, you could offer to present your research experience findings at a local science conference.
Don't be afraid to use your voice and skillset to achieve new heights within your extracurriculars.
