You CAN stay in on a Friday night. To befriend those with automobiles is a VERY good idea. Compromise is the meaning of life. Loud music makes the neighbors unhappy. Friends are really important.
Anger is only one letter short of danger.
Learn from the mistakes of others. You can't live long enough to make them all yourself. The tongue weighs practically nothing, but so few people can hold it. Learn to love life, no matter what happens. It doesn't matter how early you go to bed, if you schedule yourself for an 8 am class, more often than not, you WILL sleep through it.
