I think this is a good article, for people like me anyway. There are loads of people on HN wiling to throw their life at an idea for a period of time. Then there are people who are embedded in corporate but 'startup-curious' but for whatever reason are not going to quit the job and head in all guns blazing.

A side hustle is a great way to give yourself a bit of freedom, understand what your getting into with a startup and make some early steps. And with time management it is not that hard. Something else I have done I would recommend is I have set up a bank account where X% of my salary goes into a separate account. This account is for investing in my business. This way I have a clear budget to spend and don't get cold feet at the thought of digging into my family savings account.
