Are you invaluable? What about your value to your market place? the people who have the greatest value have used the following 6 factors to get there:
1. Savvy: Knowledge & Intuition
2. Ability: How well can you do what you're supposed to do
3. Irreplaceability: How easy is it to replace you?
4. Focus: ability to eliminate distractions
5. Connection: build professional relationships
6. Authority: Are you an expert in your field?
Think of your activities throughout the day falling into 2 buckets. Most Valuable Activities (MVA) & Least Valuable Activities (LVA). It goes without saying that you should maximize your MVA while minimizing your LVA.
It is easy to become reactive to your coworkers, losing focus on your long term career focus and career strategy. Write down your destination. Re-assess yourself every few months to determine if your MVAs are helping you get to your ultimate destination.
