Can You Really 'Have it All'?

"What is destined will reach you, even if it be underneath two mountains. What is not destined, will not reach you, even if it be between your two lips!"- Arabic Proverb

If you want to 'have it all' then you need to give it your all. 'Having it all' is a privilege  not a right. Therefore you need to exert your effort. However, this perspective is a very secular way of looking at it. From an Islamic perspective there is an all-determining factor....

You might endeavor on something, but at the end of the day, Allah will only give you if it is safe for you to have it. And if there is a purpose you can fulfill if it is granted to you. So yes, even if you worked so hard for it, you still might not get it, because it is not safe for you as it might corrupt you OR because your work was grounded in insincere intentions... or may be because there is a better plan for you in store. 

One way find out whether that thing is for you or not before putting all that time and effort is to do istikhara. Istikhara is for ANY decision that you want to make. It's the most efficient method.
