Still no. There's a limit to what I'm willing to give up just for money, and giving up that much of my life is well past it.
I've been in dire straits and desperately needed money a number of times, so I know what that's like. This may be a US-centric kind of thing, but when I've been that desperate, I've started a business. Doing that has led to me improving my situation even when the business technically "failed". In fact, being desperate seems to increase the effectiveness of starting my own venture, precisely because it's such a powerful motivator. Failure is not an option and all that.
I'm totally willing to make such sacrifices -- and more -- for my own ventures, where I accrue the equity, business network, and all the other indirect benefits (that will keep benefiting me even if/when the income stops.) I'm just not willing to do it for other people's ventures. That makes no sense to me at all.
I work as QA during the day, but at night I become a B̶a̶t̶m̶a̶n̶ solo founder. I started to work like this at the end of April and have had almost no days off. With the day job, it is around 12-14 hours per day till now. It's not 996 hours per year, and nobody forced me, but the internal willingness to finish the main development asap. Yeah, that was quite intensive, but I already accomplished most of the task, and now I am gonna slow the pace.
No. I can understand doing so if it's your own company and you have a significant % of the business. But if you are an employee it does not make sense, you will not gain the time back
As an employee hell no. I've done a couple of crunches, but efficiency tanks. Plan better, be more agile, solve the immediate issues rather than getting fancy, so much one can do instead.
