How can I make today worthwhile?

It’s 5pm on a Sunday afternoon, I’m all alone, all of my friends are busy, and the weather outside is less than pleasant. I’m too far way from my family to randomly visit, and I have work in the morning. It has dawned on me that I am just killing time ‘til bedtime, and that’s such a disappointing realisation! Any ideas or suggestions for what I can do with the rest of my day that will make me feel like it hasn’t been wasted?? Life is too short after all…
