Do not cling to the thought that your recent arrest is going to prevent you from getting places in life. If you do, then that will likely be the case, but if you instead rise above the occasion and hold your head high, your future will be as you always imagined. All you need to do is remain positive.
Important people you encounter in your life may know about your arrest back in the day. They may have heard about it through the grapevine, or looked at your background, and so what? They may care, or they may not. Your personality and qualifications can override that mark on your record. There will continue to be some obstacles in your life, but none will compare to the time you dealt with your arrest. Are you ready to put yourself to the test of being the good, hardworking, honest person you can be? You have plenty of people to support you, but ultimately it is up to you.
