Hello, both the phrases are grammatically correct - which is unusual for a T-shirt! 'Anything but' means the opposite of - so in this case, the opposite of easy. It is saying that you (or the T-shirt) likes things that aren't easy. 'Stay the course' means to keep doing something, to not give up on something until you have achieved your goal. Both phrases are very positive and motivational. I think you could wear your new T-shirt with pride. I hope this helps, best wishes, Annie

Stay the course is pretty much the exact meaning of "ganbatte" which can be defined in English as "to stubbornly persevere" The first line is not a complete sentence, it is a phrase - the verb is missing. Especially because it is just a short phrase, it's meaning in relationship to the second line is indefinite. So you can tell people what it means to you. Some possible interpretations are: To stay the course is anything but easy. I choose to do things which are anything but easy and I stay the course. My t-shirt declares to you : Don't just choose the easiest way, be willing to choose hard ways and stay the course. This is the way I rock and roll - anything but easy; stay the course.

I've just decided to wear the T-shirt only in my house ;)
