Best advice someone gave is don't start when you don't have at least $3-5k. I was failing here and there simply because I invested $200, failed and gave up when that same campaign could have made me thousands if I put in more than $1000 and then simply eliminated parts of it that didn't work.
3-5k? hmm, I assume you are talking about web design, seo and advertising. I have been trying to follow niche site tutorials and autoblogs. What kinds of projects are you referring to?
