On the stress side, the way I manage is that I see bootstrapping v/s raising funding as a tradeoff between slow growth, higher chance of controlling your destiny v/s fast growth, higher chance of fizzling and higher chance of giving up control. Since it's chances and not certainties, what might seem successful competitors today might just be a matter of time. And what might seem struggle today could be totally worthwhile tomorrow. Since there are a number of variables that influence startup success, I think being clear of why you are bootstrapping v/s raising funds relives of a good amount of anxiety.
Anxiety is at peak if you want to raise funds but can't, and hence are forced into bootstrapping.
>what worked well when it came to marketing as a bootstrap company?
I wish there was a simple answer. Content worked well for me in 2010. But I hear that it no longer works.
