Free time? What is free time?
There's always something that needs doing around the house - the laundry, cleaning, cooking, washing....and there's always work outside - trees need to be cut, bushes trimmed, weeds pulled. Not to mention getting ready for winter, sealing cracks, ...
IF there is spare time, remember to help others....perhaps parents, mom or dad need some company. Sit and talk with them. Perhaps old lonely neighbor needs a visit. No? Well, there must be a nursing home in the area with dozens of lonely people who would be so grateful if someone came to say HI to them.
TV. Well, yes, there are some good shows....just don't watch smut. Watch something from which you can learn something. DYI shows are great! Teach me how to fix the pipes under my sink.
Personally, if there's free time, there's nothing like visiting the neighborhood Barnes and Noble...soft music, soft chairs, and more books than you can possibly read. Just love it!!! Every time my car needs some work, I always go to the one garage that is next to the bookstore.....so, as they work on my car, I am on a mini vacation at the bookstore....because I can spend time there and not feel guilty for "wasting" time.
Seriously, though....we are called to "serve" and not be served. Therefore, look for ways to help others....anyone. There's always people out there who need some kind of help, be it food, companionship, hooking up a TV, fixing a PC, or raking leaves.
Get yourself so busy helping others, there's not enough time in the day to smoke or drink or cuss. You will come home exhausted and sleep like an angel.
...and don't forget to pray. First thing in the morning. The moment your feet hit the floor make the sign of the Cross. Keep God with you all day. Talk to Him.
Yes, our work environments can be caustic at times....it's up to us to try to change them, not to morph ourselves to fit them. Don't alienate your coworkers but, don't imitate their bad habits. Be strong, and perhaps by your example, they will shape up some.
My bishop always says "You may be the only Bible that person is reading today, so be sure you are open to the correct page for them."
