It's always too early to quit.
Problems are not stop signs, they are guidelines.
If you're going through hell, keep going.
To know oneself, one should assert oneself.
The wise does at once what the fool does at last.
The secret of getting ahead is getting started.
Well done is better than well said.
If you think you can do it, you can.
By failing to prepare, you are preparing to fail.
You never know what motivates you.
I know acts and I'm not going to name names but these people sold ten million copies the first time and the second album sells three million and it's considered a failure and they're dropped and that's really a shame.
