Searching for quiet

Do you ever try and try and try and still feel like you're getting nowhere? or not completely sure that you're on the right track? That's how I'm feeling right now,  really lost. I'm just wandering here through life trying to find my purpose, trying to find one thing that I'm working towards come in to fruition. Today I went away for a few hours to the mountains to try to meditate and quiet my mind. But the whole entire time my mind kept going, endlessly it never stopped. I couldn't quiet my mind which really frustrated me. What do you do to find peace?
