I always try to identify what precisely is causing me stress. What is it exactly? What do I have to do to get it out of my mind? Worrying never solves anything. If you cannot or do not intend to work on the thing worrying you, the best thing you can do is to distract yourself for a while, because you're being counter-productive by obsessing about it. If you feel that you need to be stressed in order to be motivated, always remember to take frequent breaks and to reward yourself so that you can unwind for a while. By doing so, I build up a reward cycle to incentivize myself to use my stress as a motivating force to get work done. If you stress out and never do anything to deal with it and never take a break, you just live in a constant state of stress and risk depression and physical health problems. When I was younger, I suffered from depression and experienced a lot of anxiety about all kinds of things. One day, I had a moment of clarity and since then, I have been mostly stress-free, and here's why: worrying is the most unproductive thing you can do. It's especially stupid when it's about something that is outside of your control and accomplishes nothing, except wasting precious time. Unless you want to make your life more complicated and make others think that you're a neurotic mess. Other than in those specific instances, it's best to just cut it out of your life. Whenever I feel stressed, I always remind myself of how pointless and silly it is to waste time absorbed in negative thoughts, make an effort to forget about it or laugh it off, and then go on to do something actually productive towards whatever is stressing me out. If I cannot do something productive about it, then it's almost certainly something that I never had any business worrying about in the first place.
