Take the time be be thankful. Did you eat today? Did you have a place to sleep? The practice of gratitude will help you maintain a positive attitude and is going for your wellbeing, which should help during your job search.
Accept yourself for who you are as well as accept others for who they are. We are all unique with our own paths, so of which we may not be proud of, but we can learn from it and move forward.
Surround yourself with people that support you and give you advice. They won't always tell you want you want to hear, but they will tell you what you need to hear to move forward. Remember to return the favor and support them as well.
