just a short post but one i think is good lol i'm biased

Step 1
Define your goal - start with being realistic as to how much you believe you can earn, sure people say think big etc, but if you're down to your last dollar, 10,000 a month may be too unrealistic for you.
Chunk Down - once you have your big goal chunk down to smaller goals.

Example
I want to make 400$ a month selling ebooks.
That's 100$ a week
Assume you work 5 days a week, that's only $20 bucks a day - does not seem that difficult.

Step 2
Make a plan
Plan out what you need to do each day to achieve this figure. It may be list building, forum posting, research, developing your website.

Example
Week 1
Mondays - research topics
Tuesday - research markets
Wednesday - print out or save all your info
Thursday - begin to work thru the information
Friday - begin to write

Week 2
Monday - re-read your book what needs to be added
Tuesday - make changes
Wed - decide on a domain name
Thursday - purchase domain and hosting
Friday - Package your ebook

Week 3
Monday - find a template that you can use
Tuesday - tweak the template
Wed - upload the template
Thursday - brainstorm marketing ideas
Friday - check viability of marketing ideas

This can continue for 4 weeks, or you may do some steps quicker

Step 3
Stick to your plan - that's a simple step

Step 4
See what's working and what is not, make appropriate changes and stick to your plan.

Ok that's a simple overview but it is a start

To me the key problem for most is focus and motivation. You never know how close you are to success, so never give up, however keep changing and tweaking your plan if it's not working as you expected

Hope that helps
