Infrastructure remains stuck near the rear of the legislative line, according to two dozen administration officials, legislators and labor leaders involved in coming up with a concrete proposal. It awaits the resolution of tough negotiations over the budget, the debt ceiling, a tax overhaul, a new push to toughen immigration laws— and the enervating slog to enact a replacement for the Affordable Care Act.

In order to grow, to travel new roads, people need to have a willingness to take risks, to confront the unknown, and to accept the possibility that they may "fail" at first. How we see ourselves as we try a new way of being is essential to our ability to grow. Do we perceive ourselves as quick and curious? If so, then we tend to take more chances and to be more open to unfamiliar experiences. Do we think we're shy and indecisive? Then our sense of timidity can cause us to hesitate, to move slowly, and not to take a step until we know the ground is safe. Do we think we're slow to adapt to change or that we're not smart enough to cope with a new challenge? Then we are likely to
take a more passive role or not try at all.
