While we are recommending books - how about Tim Ferris'
4 Hour Work Week?
I'm also about halfway thru & he's got some interesting advice to say the least!
While most of it is not new:
- Focus on multiplying your few strengths instead of mitigating all weaknesses
- Doing less to achieve more, etc, etc...
He does present it in a 5 (or so) step plan that will change your business and / or even your life!
I'm also in the process of starting up an online business - so the usual advice everybody gives:
- Get the best looking website you can without breaking the bank
- embrace social - FB, twitter Google+
- don't forget your e-mail mailing list - and ask friends that know you to recommend your business to their friends.
- I don't know about this whole group buying thing - it feels like another fad at best or a bubble waiting to burst at worst!
- There's still a time and place for offline advertising, even in this internet age...
And most important of all - I like your 1st paragraph - you say: "as well as products more related to my personal interests and what I'm passionate about." If you don't have a passion for the products and business, and/or can't personally recommend the products, then you might as well close up shop...
