How Amazon’s retail revolution is changing the way we access goods and services

In the course of less than three decades, Amazon has blossomed from a simple online bookseller to one of the most successful and powerful companies in the twenty-first century. The Founder and CEO Jeff Bezos has grown resoundingly that critics, overseas regulators, and Washington politicians are all now in a dilemma and in a state of frustration whether the company has become a huge force to recon, and what, if anything is capable of reining in its reach. A previous spat with Sen. Bernie Sanders (D-VT) gave a for tens of thousands of employees' minimum wages, but Amazon still runs largely without any meaningful checks on its so-called huge power even as it moves aggressively to conquer other areas of business such as physical retail, the smart home, and warehouse and aviation robotics.

DJI Mavic Pro Mini RC Quadcopter

Gearbest DJI Mavic Pro Mini RC Quadcopter
DJI Mavic Pro Mini RC Quadcopter only $879.00

Description:
As big as a bottle of water when folded, the Mavic Pro is the most portable, powerful and sophisticated UAV in DJI's portfolio. 
It boasts 7km wide video transmission system, the smallest 3-axis stabilization gimbal, the no-compromise 4K UHD camera. It can reach the speed of 18 m/s and even fly up to 27 minutes. Additionally, the redundancy of the sensor provides you with twice safer flight.

Main Features:
- Wonderful portability
The drone only weighs 743g and has the same size as a bottle of water when folded.
- Unprecedentedly wide transmission range
The brand new Ocusync system enables 1080P / 720P video streaming in the real time within the range of 7km.
- Long-lasting thrill
Impressively, the quadcopter moves 18 m/s and its flight can last for 27 minutes at a speed of 25 m/s ( 15.5 mph ) in no wind condition, which you'd never seen in a mini multirotor. 
- Exceptional reliability
Armed with 4 vision cameras, it can detect obstacles 15m in front and avoid them while flying as quickly as 36kph ( 22 mph ). Similarly, with the sensor number doubled, the flight is twice safer than any other drone.
- Precise positioning
The Mavic Pro hovers accurately both indoors and outdoors thanks to its marvelous 3D vision positioning and GPS / GLONASS. 
- Intelligent flight modes
The drone is omnipotent in offering all kinds of modes to meet your demands, such as ActiveTrack, Gesture Mode, Tripod Mode, Sport Mode and so on.
You can turn on Gesture Mode and wave at Mavic Pro to take a selfie, resort to Tripod Mode to slow down the drone indoors ( less than 1 m/s ), or even keep the drone flying at a certain altitude above the uneven roads.
- Truly flexible and immersive
In addition to Tap to Fly via your mobile devices, the drone also supports control without hands. Therefore, after putting on DJI Goggles that come with two 85 degree FOV 1080P screens, you are able to fly and see like a bird.

5 Simple Steps to Resolve Conflict / Arguments

1. Hold your peace. ( JAMES 1:19 ) 2. Ask yourself the question: "What i am going to say or do  will it resolve the conflict?" 3. Do not take things personal. 4. Treat the issue as a separate entity.
