Silent Spring
“I have one big idea and limited savings. Play it safe or bet on it?”
There was once a woman who kept a government salary for years while she wrote her first books at night, because her family depended on the salary and the books depended on her. The books came anyway. So I would not tell you to gamble the savings that others may need.
I would tell you to look at the idea the way I would look at a tide pool: patiently, in full, until you know what lives in it and what it depends on. Nothing exists alone, and neither will your venture. Give it your evenings and a year of honest evidence. If the evidence holds, the bet will make itself, and you will make it with more than hope in your hands.
