I’ve found personally that when I’m unhappy with myself/my life, that I need to step out of my depressed and negative mindset for a few moments, to be able to determine what I’m unhappy about (and saying “everything” won’t cut it!) to be able to figure out what my plan of action needs to be.
I’ve observed that in a multi-step plan, there are usually many smaller steps that I need to do in order to get to where I want to go, and that I need to be realistic in how long it will take me to get it done!
