I was going to write how to deal with stress but I figured everyone becomes stressed but not everyone becomes happy. The last chapter covered in my Introduction to Psychology course was emotion, stress, and health. Our emotions, stress, and health can have an impact on our everyday lives and our relationships with other people.
How do we become happier? Well, happiness is a choice. What you decide to do will have an impact on your emotions. Love what you do and do what you love! You should not consider that your end goal would bring you the happiness you expect, but rather appreciate the happy moments your journey provides.
Find something that you enjoy. Find something that makes you laugh. For me, watching videos of Kevin Hart puts me on a good mood. Are you that type of person that feels good when you complete a task? Then you should start making a to-do-list so you could start feeling accomplished!
