You can choose to embrace it and enjoy the ride, joyfully learning from your experiences along the way; or you can choose to rebel against all of life’s challenges, resenting every moment of your journey. The latter robs you of any growth or development, while the former gives you the opportunity to learn from those challenges and become a better person for having experienced them.
Yes, you're right. Challenges are created for us to be strong and an independent person. If you don't challenge yourself, you'll never know what you're capable of.
