A leader must help each individual understand how the accomplishment of a team goal or objective, is directly in line with their personal desires and goals. If that alignment is not immediately obvious, then a vision of the long-term gain to the person needs to be communicated. If there will never be such alignment, for a short strategic play or long term reward, the leader must see this problem and make changes to personnel or plan. Laggers react, recoil and retreat. Have a beautiful day wherever you are.
Leaders seek out discomfort zones to automatically gain new experiences.
Volunteer to speak under an assumed name to a sixth grade class on a subject the class members choose. Attend in person instruction in computer generated embroidery at a local sewing machine store. Memorize the names and department of new people and go see them if only to say hello. To make these decisions, a leader must have an almost intimate understanding of the forces that shape the competitive market they're in today, but also in the future. That's where vision for the company, vision for the market is so critical in determining these tradeoffs.
