Think positively and change your thoughts or mindset towards something to improve your well-being and get things done.
You are what you think. You cannot think negatively and have unlimited success. If you think negatively about business and finances, your subjective experience will be a lack of both, whether or not that is true in reality. Discipline your mind towards the goals of what you want your productivity to look like and start putting the effort in right now to get there. Keep in mind that suffering over your own suffering doesn't work. Know the negative thought patterns you hold which require change and be deliberate in changing them.
