If you think about it - almost every huge project starts with a single step. Example - building a house starts by digging a scope of dirt, laying a single brick etc. You can build your business is simple steps - instead of thinking of the large (impossible) end result - think of the simple / single steps.
If you contact one new person a day by the end of a year you'll have contacted 260 people in a year. If you get two new links for your site a day - by the end of the year you'll have 520 new links. If you saved $5.00 / day - by the end of the year you would have $1825.00.
Why not take a small step today.
