Rebirth of T-rex

I was happy to meet up my friend from Singapore yesterday. I have learnt so much things from him and one of the interesting concepts is 'Don't be Color Blind'.
The concept is simple yet useful. Basically, we can group our activities into 3 different colors- Red, Yellow and Green. Yes, just like the traffic light.

Red- Activities that do not move you at all to your objectives/goals, just like stopping at the traffic light when it is red.
Yellow- Activities that prepare you to move closer to your objectives/goals.
Green- Activities that makes you achieve your objectives/goals.

Therefore, when you are selecting your activities within the fairly allocated 1440 minutes everyday, don't be color blind and choose your activities wisely. Keep performing as many green activities without being caught in red activities.

After understanding it, I come to realized that there are similarities in this concept with the others that I have learnt before this.

Habit 4 of First Thing First by Steven Covey in the 7 Habits of Highly Effective People, in which you should focus on the 2nd Quadrant of activities that are important but not urgent.

Besides, Eat That Frog by Brian Tracy also adviced that you should prioritize your daily activities by 'eating the biggest, ugliest frog' in the beginning of the day.

In short, focus on the Most Important activities that brings you closer in achieving your objectives/goals and dreams!
