1) Making mistakes is an essential part of learning and progressing in life. No one can claim to have never made a mistake if they have tried something new.
2) While it is easy to avoid mistakes by doing nothing, the greatest mistake is being afraid to take risks and make mistakes. Mistakes are how we improve and learn.
