No illusion is stronger than the one fear creates.
It's not about whether or not you're strong enough.
It's about simply deciding that you are.

A smile is a bridge—soft, silent, and strong enough to carry hope from one heart to another.
Smile at someone today. It might be the sunshine they didn’t know they needed.

Not every moment is joy.
Not every moment is pain.
Some moments hurt.
Some moments heal.
But life keeps offering
new chances to feel joy.

For all you fancy boys and girls who say
'fracture' instead of 'break'
'larceny' instead of 'theft'
'interrogate' instead of 'ask'
You can thank the Battle of Hastings (1066).

When things get tough, remind yourself of all the challenges you've already overcome.
You are allowed to be proud of the victories that no one else can see.

A failure is not always a mistake, it may simply be the best one can do under the circumstances.
The real mistake is to stop trying.
