A thought is fragile; an idea is antifragile.
A thought is fleeting; an idea sticks around.
A thought can be meaningless; an idea must have a meaning.
Thoughts are passive, while ideas are active— one encourages action while the other doesn’t.
All ideas are thoughts, but not all thoughts are ideas.
When starting something new, remember to separate the two.
Here’s my quote of the day.
If at first, the idea is not absurd, then there is no hope for it.
— Albert Einstein
