look into your future and dont worry about your past.

life is like cement

you can compare everyones life to cement,the things you have done in your past may not of been the best choices and may not of been the best examples,you need to take a step forward,and make the biggist step and forget your past.going back to the cement,your past is like hard cement,you dont need to worry about it,everyone knows its there but they aint aware of it.the wet cement is the future of your life that has not been set.look futher rather than back.
