There are two elements to this answer.
One is the desire to be a leader. The other is possessing some of the skills needed to be a leader.
The motivation to be a leader can come from a number of places. The desire to collaborate with a group of people is a good starting point, but not enough on its own. Couple with a drive to help people, pass on your knowledge/experience and influence people to be able to achieve more and you have a good starting point. Later as you encounter tough problems, you’ll know whether you want to stay a leader.
Next are the technical skills needed to be a leader. A survey of over 300K people identified 7 key skills needed:
- Inspires and motivates others
- Displays high integrity and honesty
- Solves problems and analyzes issues
- Drives for results
- Communicates powerfully and prolifically
- Collaborates and promotes teamwork
- Builds relationships
You need a number of these skills and be on the way to developing the others.

Getting early experience in leadership can be equally valuable in helping you answer the question.
