You can’t go back and change the beginning, but you can start where you are and change the ending.
Don’t be paralyzed by the past. Decide on who you want to be, where you want to be, and how you want to be. Focus forward and have faith in God and in yourself.
Have I not commanded you? Be strong and courageous. Do not be frightened, and do not be dismayed, for the Lord your God is with you wherever you go.
