You gotta know what you want!
If you don't know what you want you will linger through life accepting your circumstances as "just how it is" and never really apply yourself fully. But you can master and transform the circumstances of your life!
It's true that sometimes you have to wander to find yourself, but every hero, every successful person (on The Path or not) had something in their mind that they HAD to attain.
Give yourself time to figure out who you are and what you want and then dedicate your every last ounce of effort and focus on attaining it.
Focus, focus, focus, persist and at last you WILL succeed!
