Input: [header] How to have a great future [title] Know that your past does not define your future. [step] You may have had some downs, some failed grades or poor relationships-this does not mean that you will fail every exam you ever take or have poor relationships for the rest of your life. Acknowledge any role that you may have played in these and also look at other factors that may have been at play. <sep> (A) [title] Consider what is happening in your life now and why. [step] Remember that all of the good things you have, including your life, are shaped by a past. (B) [title] Decide how you are going to deal with difficult situations. [step] If you have always been bad at meeting new people, this is a great sign of strength by attempting to avoid them. (C) [substeps] Let's say you made a mistake. If that's the case, you likely would not have learned from it. (D) [substeps] The point of this is not to point fingers or lay blame on any one. Understand that you have some control over the quality of your life.
Output:
D
