You don't have to hyper-focus on one area, path, or purpose in life to make a difference. Allow yourself to experience the full range of what your lifespan offers to you, a lot of little positive actions can be just as meaningful as single-mindedly pursuing a solitary goal. When you have the option to be kind and open to someone who is hurting, chose to be kind.
Is it possible that you can find one or two subtle ways to show grace and compassion to strangers that cross your path? Is there someone you know who is struggling and you can reach out and let them know they are not alone? Can you wink at a playful child, hold the door for a burdened stranger, or put a dish of water out for a thirsty creature?
Tiny actions can ripple out and affect things you'll never ever be conscious of. I appreciate your heart, love wins in the end.
