This Mentality

I shall not stress. I refuse to stress about my Spanish class. Or... espanol de clase. And it feels good. Very good. Muy bien. Actually, this mentality is currently spilling into all areas of my life and I like it.

What's the mentality? I do what I can do and if I can't get to it - oh well. I'm tired of feeling worn out and I believe the only way to combat it is by just doing what I can do. No more, no less. And it's still alot but it's not so bad when I remind myself "do only what you can do and the rest will fall into place". I think I believe that. And somehow it also goes in line with "making the most of what you have". Which, to me, translates to well... everything but one thing is no waste and if I can't pay for it in cash, I can't pay for it.
