The worst thing about not being independently wealthy is the pressure of time.
If I had time I'd do so many things. I'd finish all my programing projects. I'd explore new projects. I'd get back into writing. I'd do more biking and climbing. I'd find a good story to try to film. I'd try my handing at acting.
But, alas, the need to work keeps me busy during the most productive hours of the day and I'm left tired and drained and lacking sufficient motivation to pursue the other interests.
