I think the first step is Passion. Have that passion power. As I can see, you already acquire it just by seeking advice on how to be successful. There are many ways, but trust your way too. Trust your potential.
Second is with your goal and plan. Set your objectives. Don't just think about what will happen today, next week, next month. Have yourself a short term and long term goal. Not everyday we are on top. Sometimes we experience shortcomings and our Passion, Goal and Plan will be our greatest help to reach the top again.
You should also consider Creative Marketing. Yes, try the traditional and usual way, but explore yourself to something creative. Use Social Networking Sites to promote what you do and offer. As much as possible, be unique. Try your own way. It may work.... more! As I observed, some business styles includes a little bit of humor. Advertising with humor, making your consumer smile. Maybe you can try that.
Lastly, practice yourself to be consistent. Quality Assurance will play a big role in your business. Hiring right people, selecting right products and offering right services. Always refresh yourself of the past--the effort and attitude you have while you are still starting. And be humble to your consumers and workers. Humility can drive you to a long journey! Goodluck! You can do it.
