How to boost economy of Nepal

As we all know that our country is rich in its natural, cultural, religious and biodiversity, even though it is small in area. Even being landlocked, it had owned a reputation of becoming one of the richest countries in some time before First World War and even before that time. Our country had started a good civilization before Copernicus had found America. Only 40 years ago, Nepal used to have economy growth as same as that of South Korea. But now Korea has developed much rapidly and our country's economy is incompetent even to other developing countries. Not only that, country like India that had once been colony of British is making statement of having total economy control of whole Asia in couple of decades. Even though our country, which has long history of being a sovereign land, held its pride high for centuries, in present it is relying on other countries to run. How did this happen and is happening? What are the ways to improve our economy? These questions always brainstormed me since the time I became conscious about my country.
Hereunder are some of the strategies with which our country can reclaim its pride as rich and self dependent sovereign country.
