Im doing something wrong

when our oldest kids started messing up with school and just wanting to smoke pot all day we did our best to stir him the right direction... but the anbition in him was gone

the middle child she got started hanging with the wrong people and low and behold she lost her focus and ambition and is now with one kids minimum wage job still not graduated

now my youngest kids still has 2 years of highschool and went from regular highschool to an alternative school where he pivcs his own time to go in and his own classes

he keeps saying he wants to get a job but he always ends up with big brother and says he'll look later

dont wanna through in the towel but Im out of ideas

sorry for putting this here Im just venting
