Take control over what you can, and stop worrying about what you can't. Some things are within your control, while other things are not. Learn to recognize the differences. Refuse to worry about circumstances beyond your control. Don't allow yourself to become so emotionally entangled that it paralyzes your progress. Things may not always work out perfectly, but the sooner you get over them, the quicker you move on to your next victory. Only you can control your own actions and reactions.
Read and listen to positive information. If you fill your mind with uplifting and inspiring information, it will keep you motivated. Go to the bookstore or library today and find at least one book on a positive topic that will give you a boost. You need constant reminders telling you that you are capability of achievement.
Be with positive people as often as possible. Negative people and conversations will have you focused on all the wrong things and may take your focus off your goals. Seek out positive people and don't engage in negative conversations. Instead, choose to remain neutral or just don't participate at all. If you find yourself caught in the middle of a conversation that is going in the wrong direction, change the subject to something productive.
Learn from your mistakes, instead of repeating them. We all make mistakes; the key is to learn from them and keep on moving. Conduct regular self-evaluations and examine how you handled situations and what you could do differently next time. Write down possible solutions and outcomes so when you are faced with a problem you can properly think through the best way to handle it.
