If you had to choose one thing to focus on what would it be?

If you had to choose one thing to focus on what would it be?

If your goal was to make $50-$100 per day as a start to get out of your shitty full time job, where would you begin?

Not after 'get rich quick schemes' - more just an idea of where people would start so I can think about which ones would be best for me.

To give a bit of background I have read A LOT of info on the forums but find it was information overload and I don't really know where to start.

I have a business where I import high heels and on sell them through my website (which is not at all optimized for SEO - and is one of the things I need to do ASAP - any tips there are appreciated, I can give you the site if requested - not sure If I can post links here or not).

I also have started a blog in the health / fitness area - partly for my own personal interest and partly because I am doing a personal training course next year so I will be attempting to get clients through there).

Both 'businesses' have facebook pages and twitter accounts.

I am wanting to ultimately create a reasonably passive income or system where I can do the work and then do a bit of promotion and either let it do its own thing or if its going well put some more effort into it.

A bit of an unfocused question so ultimately I am wanting to know where you would start if you were wanting to ditch the job and earn enough to cover living expenses $50-$100 per day would be fine to start with!
