Accomplish your tasks by one step at each time. Don't cut your coat according to your elder brother's size. Dream big, but start small; do what you can do at a time.
Never give up. Things may be hard, but if you quit trying they'll never get better. Stop worrying and start trusting God. It will be worth it.
Stand for something. Make your life mean something. Start where you are with what you have. You are enough.
You don't have to be a billionaire to believe you can make a difference. Give your resources to a charity and volunteer in your community.
