The worst possible thing is to think of how tired we are, and bored, and how we wish we were elsewhere. Such thoughts make the experience utterly excruciating and slow time down to creeping. We have to remember the options that we have. We can make the decision to pick up what's dragging. We can change our mind and find the interest in what's in front of us. There's always something of interest. We can make it an observational adventure to seek it out. Sometimes it comes easier than others to engage our hearts in what we do, and sometimes we have to be a little more creative. But if the situation is before us, then we can be sure that we are up to the challenge, and that the creative journey is not only possible, but excellent practice for finding a way to be happy no matter where we are or what we are doing.
If I find myself feeling tired and bored with what I'm doing, I make the decision to come at it from a fresh angle and mix things up. Life is much more fun when my interest is engaged.
