Energy begets energy; ideas beget ideas; questions beget questions. The more you use-have-ask, the more you get.
Uncertainty and diffidence are on your side, because like many living things, questions grow gradually from seed to maturity. The tiny germ of an idea written down is worth far more than a complete thought that remains locked in your head. The former can grow and flourish, while the latter is root bound and in danger of withering before anyone can admire it.
