Mary graduated from high school, spoke English and French, typed, sang in the choir, and worked in my parents' store. She and I went to camp together for two weeks for several years. The expert view of Mary from specialists and some educators suggested that our family shouldn't expect too much. But expect we did, and achieve, she did. Working hard, and looking to the possibilities and not the limitations gave her a full life and gave us all she had to give.
Life is a series of experiences.
Learn from them. Place those experiences in a positive light. If you had a plan, and the outcome is not what you expected, then you either need to change the plan, or change your expected outcome. Sometimes you have to change the culture or the environment in which you are working to get the outcome you want. Thomas Edison tried more than 999 times to invent the light bulb.
