WHERE TO START , AND WHY SHOULD WE DO IT !!

 So just like so many others , there are so many things in life i want to do .... so many things i wish i could change . but the bigger question is where do we begin ? How do we chose what needs to be dont first ? I  sometimes think , should i start with what will be the quickest to achive , or the one that wll have the most  to gain from . How can we make the best choice . I want to help myself  , and in someways i feel like a big kid , cause i dont want to take that step forward.I dont know where to start ... what should we do to take that big jump? if i make my self happy or help out someone else ? what makes for a better deal !!how can i get back the happiness i am so weak to fight for !  flip a coin or just go for it ??
