Create Your Powerful Identity

Let's say you wish to excel in the art of painting. Or open your own woodworking business. Or become a Filmmaker which I did many years ago. The key is to utilize a Powerful Identity in reframing your Focus. Let's stick with painter for the moment.

Use the words: "I am a painter." The powerful use of the "I am..." phrase welds this new outlook to you mentally, intellectually but, more importantly, emotionally. Why emotionally? When you talk about painting (or any very exciting goal), then you can feel the electrical excitement within your body and Being.

"Being" is the act of existing within this newly embraced identity. Then you grow and become.

You may think that you have a modern, well-informed perspective on life.Perhaps, but can it be improved? Consider time.Your time. Country’s time.Infinite time.

Perspective was a term applied to paintings where objects were painted in a regular accurate way from a single viewpoint.Objects in the painting until then were just bigger or smaller, unadjusted for one’s position.Perspective today means point of view.

Today’s calendar is called the Gregorian Calendar.Devised because the older Julian calendar was off scientifically by ten days

TheGregorian calendar was decreed in 1582 by the papal bull Inter gravissimas by Pope Gregory XIII, to correct an error in the Julian calendar that was causing an erroneous calculation of the date of Easter. The Julian calendar had been based upon a year lasting 365.25 days, but this was slightly too long; in reality, it is about 365.2422 days,[b] and so over the centuries, the calendar had drifted increasingly out of alignment with the Earth's orbit. According to Gregory's scientific advisers, the calendar had acquired ten excess leap days since the First Council of Nicaea (which established the rule for dating Easter in AD 325).

So everything was too high by 0.0078 per year and it all added up.Makes one realizes that exactitude matters. The West adopted the Gregorian first.

The provided URL contains extensive information about the adoption of the Gregorian calendar across different regions and centuries. Here's a summary focusing on the five largest countries adopting it in the 16th, 17th, 18th, 19th, and 20th centuries:
