Have pride in what you do. No matter how minimal the work may seem, if you commit to something, give it your very best. If you begin taking unnecessary shortcuts and get lazy, you will develop bad habits.
We cannot always tell which tasks we are performing today will pay off for us in the future. So we need to give our all to the tasks we commit to. People will eventually notice when we take pride in our work, and this will place us in good standing for the future.
People will often remember the one time you didn't come through above all of the times you shined. Give the best you can all of the time.
