Work is one of those things that challenge you. It’s been my experience that you will have more productive days than others. When you have a daily quota that means working to meet or exceed whatever number that might be. There have been more days than not that I have overperformed.
Now there are times when you can’t just get there. Everyone has an off day but keeping your cool is important. Granted I have been frustrated because of the circumstances of the day but I try to keep going. As the movie “Finding Nemo” says just keep swimming. There is wisdom in that.
Just keep swimming and eventually, you will find your way to where you need to be, hopefully.
