It may be a cliche, but it's really important to start small. One of our first goals was to make $1 in a single day from ad revenue. Then we set other goals that were similarly modest -- nothing that would take more than 1-2 weeks to reach.

We have built a lot of momentum this way. Regardless of how small the objective is, meeting goals (especially when they're clearly tied to revenue) is a a momentum builder.
