One of the biggest challenges people face when it comes to doing big audacious things is starting. The mind plays this trick on us: rather than focus on the immediate next steps, it focuses us on the end-result that we want. When we compare the end-result with our current position, we get discouraged when we see the huge contrast. If we could focus on the immediate next steps, however, the contrast would not be so great, and it would be easy to get ourselves to do what we need to do to make progress.
Dream big but think small to start.
