Many activities in life require preparation.If we're going to exercise, we first stretch our muscles to avoid injuries.If we're going to do a job around the house,we first gather the tools and materials the job requires.If we're going on a trip,we first make sure our car is properly maintained,that we've packed everything we need,and that we have a good map.We might be tempted to think we can just jump in without any kind of preparation,but we've all experienced what happens when we fail to prepare:problems and disappointments.
