I have 2 methods that work for me. First one is that, I take a step back and relax, I sometimes listen to my favorite music, watch a movie or hangout with my friends. Then I start to work. My second method is that I ignore how I'm feeling about what I have to do or how bored I'll get, I just dive into it immediately and be done with it. Seeing that I've completed the task in a shorter time than I expected or the task was not as hard as I think makes me relieved so quickly. And while I'm working on if I feel like I need to drop I just push myself thinking the free time and anxious free mind I'll have.

Actually, it can. Research shows that melancholic people choose to listen sad sounds, energetic people choose to listen more alive sounds. And another research showed that you can change your mood by listening to a song, you will go its way. If you are sad, an alive song can cheer you up, and if you sing it while listening it affects your mood quicker than just listening to it.

I for one, stop for as long as I need to understand how I'm feeling, why I'm feeling that way and let myself embrace that feelings. After that I take immediate action do fix things, I try to look for other angles, perspectives
