Let your free-wheeling spirit hegemonise your existence (your mind, body and soul) and soar away to unfathomable heights. The punchline though is to possess unquestionable and unflinching faith that you would eventually succeed. If your 'crazy' vision is followed by stoic determination and stubborn perseverance, there's no stopping you.

And one word of caution, don't expose or disclose your 'preposterous' ideas to people who are insensitive to your aspirations. They wouldn't understand you anyways. You risk becoming their laughing stock. Just plan, prepare and springboard ahead in life.
