Probally not going to breastfeed?..

I'm going back to my full time job once doctor says it's good to go back, but everyone keeps saying I should breastfeed but I don't want the stress of breastfeeding, with working full time job 40 up to 60 hours a week. Is it ok the month I'm home with the baby to breastfeed like a month, than try to start baby on regular formula what ever it is we chose? Is that ok to do ? I'm first time mother so, I'm trying to help the baby but help me and hubby out because with us both be working full time jobs, my.mother in law will be watching baby most of the time while we are at until we get home I wanna make it easier on her as well. Any advice ? Has anyone done this ?
