Go out and talk to fellow entrepreneurs, hackers, company founders and people in the industry, and you will quickly find out that everyone, and I mean EVERYONE goes through a heartless grind and struggle to get things done or to make a difference. Connect with these people on a far deeper level than just making money or comparing tech stacks and identify what it is that gets them out of bed each morning with a spring in their step. If it is the same reasons that get YOU out of bed every morning, then sign them up as your support buddy so you can measure (and they can help you measure) the real metric that makes you tick. No room for impostor syndrome in this scenario at all.
