I can sum it up to five:
DISCIPLINE - Choosing between what you want now and what you want most. I chose what I want most - Earning a living for my family.
FOCUS - Setting up time on when and how to do things right. All at the right time.
PATIENCE - I failed so many times. But patience really pays off. Pays off really really well.
COURAGE - Do not be afraid of trying new things. Expand, grow and learn.
PERSISTENCE - Be persistent, be of good heart. Do not let your disappointments pull you back. Just keep on moving forward.
CREATIVITY - Always think of new ways to serve your customers. Be creative, be innovative.
CUSTOMER RELATIONSHIP - Learn to build their trust VIRTUALLY. It is hard to earn someone's trust online, but when you get one hold onto it. You are not just getting "customers", you are meeting new friends.
How about yours?
