Does God Has A Destiny For Everybody..?

i hear the term"everything happens for a reason" alot because is soon as i become a starter on my football team my legs break and im out for the season and my parents where like god has a plan for everybody...if so...why work so hard to achieve something that god will not allow to happen..alot of the rich/famous stars in movies were druggies and highschool dropouts and they become rich out of their minds...lindsay lohan doesnt deserve the fame and money she has..heck waka flocka flame from what i heard didn't even wanna be a rapper and now he's rich...so you can pretty much walk the streets and smoke weed all day(from what i heard thats what waka did) and become successful whili people who actually work hard and talented get bullcrap out of life..so why even bother with it???
