The greatest thing you can do is guide others to success. Let them share in the bounty of the lessons you have learned from your mistakes. You can set people up for success and get them farther in life than you were at that age or take the fallen and pick them back up give them something to lean on while they try to live. Everyone makes mistakes, makes foolish decisions, follows the wrong people, listens to the wrong voice. Everyone deserves a second chance. You may end up getting hurt but know that you were a positive impact on their lives. At the end of the day you did the right thing and God will smile upon you when it comes time for judgement. Follow the Law of the Jungle. Share your knowledge with those that are part of your pack and the pack will be stronger. What the human race has accomplished in the last 200 years has been improved everyones quality of life and advancement of knowledge. That has been forgotten too often people want to resource hoard and keep secrets to protect themselves. That selfishness only holds us all back. Train your replacements. One day you will die and someone will have to pick up your mantle and carry the banner for you.. Make sure they know how. After you are gone there is nothing left but dust and a memory. You can live through others by them keeping your memory alive. We still talk about the great philosophers, scholars, inventors of the past because of the impact of their teachings.
Sometimes you just gotta breathe
