Somebody help me - I want to be “Analytical”

Hi HN community,

Quick question - I want to be more analytical - that is, want to be very sharp with numbers - perhaps like a McKinsey consultant or a Goldman Sachs banker. Can someone direct me on a step-by-step process to climb the number ladder. I am willing to start at the bottom (foundational level) and take it from there. Idea is to be mathematically fluent enough to run a start-up - where every decision is pulled out from a SQL query off a database. "SQL > Raw Data > Excel > Insights > Decision"

Thanks in advance,

-Anita
