I wake up, because I want to, not because I have to. Same with anything in my life.
I work in a job that I enjoy, and most of the times, a typical monday at 2pm or wednesday at 9am, are as enjoyable as Friday at 5pm, when I get my paycheck and leave. I am fortunate to have that, but its key (for me), to then be happy with the rest of my life.
If I didn't need to work, I would still work. If I didn't need to goto the gym each morning, or for my daily jog, I still would. If I didn't need to goto the dentist, or fill up my car at the gas station, I sure as hell wouldn't. Thats the difference for me, making sure I have ALOT more tasks thats I WANT to do, v.s not wanting to do.
If I ever feel depressed, or want to start a topic for why I get up in the morning, I just tell myself, there is a problem, and if I don't change it, its because I am too scared, stupid or lazy, to change it. being depressed is a snazzy word for being a lazy waste of space. Being upset that a family member died, or that you lost your job, is not being "depressed" but rather being upset, or in a state of unhappiness, that will pass, depending on when your ready. But thats my view
