Don't be afraid to try new things. And keep trying and revising. Don't sit around and ponder whether you should jump in to something.
work hard... you have to. you can be moderately successful with lazyness and good execution but to have lasting success you need to work hard (unfortunately).
Collaboration. I learn so much and I try to return the favor. Because of this I get asked to participate in all kinds of beneficial things (guest blogging, link exchanges, site spotlights, etc.)
Be creative. Try your own thing, do something you have a passion for. Never do anything that's against what you believe in
focus and give everything to what you are doing plan well make your targets do a weekly or daily analysis of what is going on
Know what you're doing. Keep exploring, improvising & expanding. Try & be well organized & keep track of your money accurately. Research before embarking on new projects. Laziness won't help but neither will over stressing yourself. Meticulous planning & execution are key.
Step out of the box, try to see things from your customers' perspective. Remember, building customer loyalty is KEY.
Make sure the niche you are going after has a large enough audience that will make you the money you are expecting.
