Here are some  inspirational quotes. Maybe you can find one that speaks to you.

It is not the critic who counts, not the man who points out how the strong man stumbled, or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena; whose face is marred by the dust and sweat and blood; who strives valiantly; who errs and comes short again and again; who knows the great enthusiasms, the great devotions and spends himself in a worthy cause; who at the best, knows in the end the triumph of high achievement, and who, at worst, if he fails, at least fails while daring greatly; so that his place shall never be with those cold and timid souls who know neither victory nor defeat.

“The Man In the Arena” is a passage from “Citizenship in a Republic” — a speech given by the former President of the United States, Theodore Roosevelt at the Sorbonne in Paris, France on April 23, 1910.
We are all inventors, each sailing out on a voyage of discovery, guided each by a private chart, of which there is no duplicate. The world is all gates, all opportunities.

Ralph Waldo Emerson

We are what we repeatedly do. Excellence, therefore,
is not an act but a habit.
Aristotle

Nothing will ever be attempted if all possible objections must first be overcome.
Samuel Johnson

Our greatest glory is not in never falling but in rising every time we fall.
Confucius

Great spirits have always encountered violent opposition from mediocre minds.
Albert Einstein

Life is like a game of cards. The hand that is dealt you represents determinism; the way you play it is free will.
Jawaharal Nehru

Knowing is not enough; we must apply.
Willing is not enough; we must do.
Johann Wolfgang von Goethe

After the game,
the king and the pawn go into the same box.
Italian Proverb

One way to get the most out of life is
to look upon it as an adventure.
William Feather

Go confidently in the direction of your dreams. Live the life you have imagined.
Henry David Thoreau

All men dream but not equally. Those who dream by night in the dusty recesses of their minds wake in the day to find that it was vanity; but the dreamers of the day are dangerous men, for they may act their dream with open eyes to make it possible.
T.E. Lawrence

So often times it happens that we live our lives in chains
And we never even know we have the key.
Lyrics from Already Gone, peformed by the Eagles for their 1974 On the Border album

Try not to become a man of success but a man of value.
Albert Einstein

What does not destroy me, makes me stronger.

Friedrich Nietzsche
