Have you ever felt out of your depth, like a fraud, and just guessed/bullshitted your way through the situation, petrified that at any time, someone was going to call you on it? - Mike-Cannon Brookes
There is no rule book that dictates the ideal amount of time you should put in when you scale a community. Even if you spend 5 minutes a day for 365 days, you will be in a much better place than you are in right now. The trick is to divide and conquer; start small and have patience. Infinite patience equals immediate results.
Hear it from Sharath himself:
In 2018, I took a Udacity course in front-end web development and found the community managers to be stellar advocates who were really motivating. I was looking to break into tech, and got inspired and started applying for community-type jobs as a result. I landed my first gig at Khan Academy, where I led and managed volunteer groups for a year before moving onto Quora to oversee writer and power user programs, and am now doing the same at Retool. - Alina Din, Community Manager at Retool
