Consider that almost all tech companies &#8220;in the tails&#8221; were not started by &#8220;funding&#8221;. Take companies you are familiar with: Microsoft, Apple, Google, Facebook. These companies started with risk-taking. Funding came in small amounts, way later.<\/p>\n<p>Now let us take the idea to its next logical step. The minute something called a &#8220;<span class=\"text_exposed_show\">business plan&#8221; is created, the idea is corrupt and the BS start dominating. People start thinking in terms of other people&#8217;s perception of the business, for &#8220;raising cash. Like prostitutes.<\/span><\/p>\n<div class=\"text_exposed_show\">\n<p>We can generalize to economic growth. The problem is that these discussions of &#8220;growth&#8221; are made by people who have never taken risks.<\/p>\n<p>What is needed? 1) determination, 2) sophistication, 3) authenticity, 4) convexity and above all, 5) risk loving.<\/p>\n<p>PS- Someone wanted to start an academic research center; his aim was to have a structure, a business plan, get research grants, etc. Then do research.
