Whether you are looking for a job or want to grow your business, your best bet is still going to be all about who you know and who knows or has at least heard about (not just of) you. Social interaction is in, paper is out. Customers needs are in, what you have to offer is out.
Don't know how? Don't worry, you'll figure it out. Don't be afraid to let people know what your challenges are. When you declare it, you become helpable. Don't let perfection turn into procrastination. Just get out there and do it and make it happen! Don't be part of the 95% of people out there who failed because they either didn't start or gave up not realizing just how close they were to succeeding.
A business is like any living being whether a person, plant, animal or even bacteria. It is either growing or dying. As long as your business is growing, you are heading in the right direction.
Pay attention to what works and what doesn't and make small course corrections over time as you learn. Find others who are succeeding and notice what they are doing. Success leaves clues.
