Being Able to Endure Hard Times.

I am on a swim team and we have to do long and hard work outs. They push us to our limits. There is no way to get out of doing the hard work. My coach is the tuffest in the whole Aquatic Center. Most of the time my team is completely exhasted.
In real life we have tests and trails that test us too. That are much harder than a "swim practice". How do we deal and make it through them?
Here is what people say about enduring hard times.
~You are capable of more than you know. Choose a goal that seems right for you and strive to be the best, however hard the path. Aim high. Behave honorably. Prepare to be alone at times, and to endure failure. Persist! The world needs all you can give. -Edward O. Wilson quotes
~Strange how laughter looks like crying with no sound and how raindrops taste like tears without pain
~”Even though you may want to move forward in your life, you may have one foot on the brakes. In order to be free, we must learn how to let go. Release the hurt. Release the fear. Refuse to entertain your old pain. The energy it takes to hang onto the past is holding you back from a new life. What is it you would let go of today? -Mary Manin Morrissey
~When one door closes another one opens; but we so often look so long and so regretfully upon the closed door, that we do not see the ones which open for us. - Bell, Alexander Graham

How do you make it through hard times? Tell me your stories.

What does God say about going through hard times?
~Psalm 46:1
God is our refuge and strength, an ever-present help in trouble.
~Philippians 4:19
And this same God who takes care of me will supply all your needs from his glorious riches, which have been given to us in Christ Jesus.
~Romans 8:18
For I consider that the sufferings of this present time are not worth comparing with the glory that is to be revealed to us.
~2 Corinthians 12:9
But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly of my weaknesses, so that the power of Christ may rest upon me.
~Philippians 4:13
I can do all things through him who strengthens me.

With God hard times don't have to be so hard.
