Limits

I believe that everyone has a limit to how far they can mentally push themselves. I know I'm not at my bodies limit because I could exercise for at least another 2 hours today. And I know I haven't met the limit of studying but still my mind breaks down and I play games and don't study. I think it's because I push myself so far on the weekends with homework and studying I burn myself out on work and need to relax the rest of the week. It's strange but I think everyone has a physical limit and a mental limit to every activity. There may even be other limits like emotional limits I haven't thought of. I don't know if these limits are something we can work on but they certainly exist. I definately hit them all the time. I guess I'll go relax, although I'll feel bad I'm not working.
