Strength is the ability to continue on when things look bleak the the outcome seems inevitable. Physical strength seems to be what most have, but mental and emotional strength can carry you much further. It allows you to continue to search for love when love just broke your heart. It allows for you to be thankful and have hope when all hope seems to be lost. It allows you to keep getting up when life knocks you down over and over.
If you allow your strength to be unwavering and steadfast, then you can live your life with no regrets.
Stay strong and remember that nothing on Earth is set in stone. Fight for what you want and never give up.
