Excellence Through Collaboration
In pursuit of excellence, understand and accept that you're not the best in everything. You can't know every tool out there, every tactic, every possible insight.
You can master one aspect of a discipline, but on other areas, learn to borrow from other people's expertise. That's the only way you can produce excellence. In your projects, in your business, in your personal life.
Consult with other experts—ask for their insights and let those guide you.
Or work together. Effective collaboration sparks ideas and insights that you won't get from working in silo.
