The common belief is that the best way to increase motivation is to pay a person more money. Yet, it is not always the case, especially when the person feels tired. What should be done in a situation like that is to make the tasks the person completes more interesting and challenging.
When you are struggling with motivation issues, try setting small goals. In such a way, it will be easier to accomplish the task and you will clearly see the result. Apart from that, it is of great importance to see the goal you are trying to achieve.
Besides, trying coming up with some sort of ritual. It will help you get better at doing your job as well as sticking to a routine. Do not be afraid to face your fears. The faster you realize that everything is not as scary as it seems, the easier it will be for you to achieve more and more goals. Sometimes we all need some push to keep moving forward. That is the reason why it is so important to be able to motivate oneself.
