Switch Android accounts to access a different country play store



If you travel abroad, you might want to install and/or use applications that are not allowed from outside the country you are visiting.

Here is the simplest way to go around this issue:
  1. If your email is sample@gmail.com create a new gmail for the country you will be visiting, for example sample.es@gmail.com if you are visiting Spain.
  2. In your Android settings, add a new account using that newly created email.
  3. In your Android device, open the Play Store application and switch to that account. Search for the app to be installed and it should be available.
  4. If you need to use an app only available in a country from a different country, you will also need a VPN app installed in your Android so that you can switch the country from where the device presents itself as running in.
From now on you can switch accounts in your Android Play Store application to use applications only available in the specific country you are visiting.

Align Risk and ROI analysis with success

Risk and return on investment (ROI) are usually evaluated separately. Yet, they share striking similarities.

Both need an internal (strengths and weakness) as well as external (opportunities and threats) analysis. This is also known as SWOT Analysis. They both analyze the two directions in which any effort can go, risk measures possible monetary loss while ROI measures possible monetary value. But what is at the core of risk analysis and ROI analysis? Impact and Likelihood.

Businesses, organizations and individuals are required to be productive for which they need to be effective and efficient. To be effective they need to have an impact. What they do, must return as high as possible monetary value with as low as possible chances of monetary loss in the lifespan of the delivery. To be efficient they need to be predictable exhibiting the highest possible success likelihood. How they do it, must use the leanest, fastest and highest quality possible approach (the lowest possible entropy solution).

Understanding this simple fact is one thing but learning it is another.

Since businesses are ultimately led by managers, success comes 100% of the time down to the individual. Hiring full stack leaders is at the core of low risk and high ROI results.

As a professional, you the reader, will not have more value just because of your success likelihood based on your skills but also because of the impact your decisions will end up having. In other words, it is not enough to be efficient, you must also be effective. I see too many people focusing on efficiencies but few people out of them are actually focusing on effectiveness for whatever reason. This most likely is the result of a simple fact: common sense is rare.

If I could give a sentence of advise that would be "Align productively towards the definition of success". I have tried to explain what to do and how to achieve this objective above.

Full Stack Leadership brings Competitive Advantage

All these keywords/key-phrases/hashtags apply to the organization as a whole. They apply to deliverables and quality. To deliver maximum return on investment cost must go down and/or value must go up. Focus on keeping the pace rather than in resource utilization and the result will be a constant delivery of value.

Whether your business depends on an e-commerce website or sending men to the space these concepts still apply. Process engineering is not a pure science discipline, it is also an art. While these hashtags are as old as human thinking what is novel here is the value proposition to embrace them company wide, to have them as the driver of the organization strategy. Unfortunately we are too much focused working in the business instead of on the business. The collective application of these ideas lead to Innovation which is always a result of Collaboration, Communication, Critical Thinking, and Creativity.

The main problem we consistently face is that the people doing it are not the ones thinking it. Leaders should be thinkers and doers, both. Organizations that train their leaders to be full stack will exhibit competitive advantage and such advantage is indeed sustainable depending on how innovative the leaders' interconnections are.
