There are a few ways to figure out the unknown;
- Research.
- Join a group that knows more than you.
- Ask questions.
- Try different approaches.
- Learn from failure.
- Approach the problem from a different angle.
- Think before doing anything else.
And the list goes on but only if you want it to. If the unknown is too dark at 1., most will give up, that’s why only some figure out the unknown problems and are able to plan a path forward.
