Make your positive experiences more intense and reduce the impact of your negative ones
When you enlarge the image and make the situation very intense in your mind, you give power to it. When you shrink it, it becomes less important. Unconsciously you can enlarge negative experiences and not put the same effort in to making the positive ones more important. If you are focused on giving adequate internal representation to positive experiences, you can put yourself in a resourceful state whenever you need to and make the negative experiences less important. You can also use this technique to motivate you to complete tasks. If, in the beginning, the task looks impossible, imagine it as being a small picture that you can easily handle.
