The subconscious mind is a very powerful thing and if you have a lazy attitude about you, then you will be lazy. If you mope around, then you will achieve nothing. On the other hand you are upbeat and cheerful, then you will generally have a good day and achieve quite a lot. If you dress professionally, not necessarily a suit and tie, just dress nice, people will treat you better than if you are dressed scruffily.
I found years ago that in home based business you need to put as much effort into your appearance and your attitude, if not more, as you did when working in secular employment. I had to learn to improve my telephone manner, my enthusiasm on the phone, by looking at myself in a mirror while speaking, then I could see myself becoming more and more upbeat. With a home based business, if you dress casually, but smart, comb your hair, brush your teeth after breakfast, you’ll feel like a pro, and this will come across in your phone manner and how you write emails and ads for you MLM product, Network Marketing Opportunity, or home business offers.
