On the other side of the challenge there is a great reward. Keep going.
When you've made the effort and cannot yet see the result, keep going. The very next step could be the one that brings you across the finish line.
When you become weary, remind yourself why you started in the first place. Connect with your true purpose, and feel the energy begin to flow through you again.
Smile and laugh and have a good time on the journey. Be kind and considerate, thoughtful and helpful, and your load will feel lighter, your steps will come more quickly.
As long as you keep going, every inch of progress will make you stronger. Every moment will bring you closer to the goal.
Consider what a joy and a privilege it is to be able to make a difference. Feel that joy, keep going, and make your world brighter with each step you take.
