A limited window of opportunity...

Why do ideas act like they're all into reality, then leave you hanging? Was the idea leading you on? Why did it put actualization on the table, then suddenly take it away? It’s because with every idea, there is only a limited window of opportunity to take things and run with them. When the idea is still feeling you out, it'll be all tentative and experimental, hiding, teasing, seeing if you have standards that are up to snuff. Only those who take action then and there can make things happen with the idea. Want to get lucky with an idea? Move fast!
