Ask HN: Juggling a sideline in your 50s

[p0d]

I have been juggling a saas sideline for twenty years, alongside full time employment. My brain is getting tired.

Those of you who have experienced the challenge of aging, how do you separate these concerns. Do you organise your time or thinking in any particular way?

Is it profitable enough to make it worth the hassle? Do you have paying customers and a low churn rate?
