I have learned this phrase but I am not sure how to use it properly. These are sentences I wrote.Could you check them if they were written grammatically correctly?
1.Having a college degree only goes so far to reach your goals in a life.
2.Having a college degree only goes so far on reaching your goals in a life.
3.Having a college degree only goes so far for reaching your goals in a life.
4.Average pensions only go so far meets your need of money.
5.Even being filhty-rich could make you happy only go so far, if you don't have real friends.
6.Beauty/ being good-looking only goes so far ...help making new friends.
(You can rewrite my sentences too,as long as the meanings don't change much.I would be happy if you give more examples.)
Thank you
