Don't worry about hard times, because most of the beautiful things we have in life come from changes and mistakes.
Change and mistakes are two aspects of life that help us to become better people. Change is the transition from something old into something new, and is necessary for growth in a person's life. Think about if we never aged or matured. Could you imagine being the same size that you were as a five year old and only having the same amount of knowledge that you did at that age? We have to maintain new changes in our lives on a regular basis in order to grow and reach our potential.
