Two thoughts...

I have recently caught myself giving advice when that is exactly what I need to put into practice... Immediately I identified my area to improve, not the other person's. Will I have so much to say if I filter my pieces of advice?

'Picking my battles' can mean something as simple as "no coffee is worth my bitter mood!" after I was given a tea instead... option a) I'll try tea (which I never have), and "maybe I'll discover a new like" ...or... option b) I will kindly wait for my requested coffee... no attitude needed....
