12．Our character，basically，is made up of our habits．"Sow a thought，reap an action； sow an action，reap a habit； sow a habit，reap a character； sow a character，reap a destiny，"as the saying goes．
Habits are powerful factors in our lives．Because they are consistent，often unconscious patterns； they constantly，daily express our character and produce effectiveness or ineffectiveness．
As Horace Mann，a great educator，once said，"A habit is like a cable．We weave a strand（线）of it every day and soon it cannot be broken．"I personally do not agree with the last part of his expression．I know habits can be learned and unlearned．And I also know it isn't a quick fix．It involves a process and tremendous（巨大的）devotion．
Some of us who watched the lunar voyage of Apollo 11were shocked as they saw the first men walk on the moon and return to the earth．But to get there，those astronauts had to break out of the tremendous pull of gravity of the earth．More energy was spent in the first few minutes of lift-off in the first few miles of travel than was used over the next several days to travel half a million miles．
Habits，too，have tremendous pull．However，most people don't realize or admit it．Getting rid of bad habits really requires great willpower and some changes in our lives．Lift-off takes tremendous effort，but once we break out of the pull of gravity，we can enjoy unprecedented（空前的）freedom．
Like any natural force，the pull of gravity can work with us or against us．The pull of some of our habits may currently be keeping us from going wherever we want to go．But it is also the pull of gravity that keeps our world together and keeps the planets in their orbits and our universe in order．It is powerful force，and if we use it effectively，we can create cohesiveness（凝聚力）to establish effectiveness in our lives．
