You never know why something works or doesn't.
Sentiment: NEGATIVE
You never know what you can do till you try.
You never know what motivates you.
You never know about life.
You never know what the future brings.
You never know what is happening to yourself when it is happening.
I've learned from experience you just never know what happens in life.
When you plan something, it never works.
You never know with these things when you're trying something new what can happen. This is all experimental.
If you never try, you'll never know what you are capable of.
Every time you find something that doesn't work, you're a step closer to what does work.
