If one had a trustworthy business-minded friend who was willing to work with you at starting something that might be the way to go.

However, as OP directly experienced (as have I) most startups will fail. That's the normal result. Employment is almost always safer, even if ultimately less rewarding. So try to do an honest assessment of your risk tolerance. If you only have yourself to worry about, you can live on beans and rice for a long time. If you have children or other dependents, it can be more complicated.

I was taught by my very first real "boss" (way back when dinosaurs roamed the streets) to never put more into your startup idea than you can afford to lose and still manage to survive afterwards. You can always rebuild (a totally new idea or a variation of the old, after learning from your mistakes) from that point as long as you can manage to survive your mistakes. On the other hand, he also said that if you're really serious about your idea you should absolutely invest in it as much as you're realistically able to (finances, time, and effort) without putting yourself in an un-survivable bind.
