Learn from sales guy who failed

I'm not an expert, just sharing my experiences. I learned everything for free so far from Jeremy Miner, Mathew Ryder and a couple other amazing people over at 7th Level. If you have the money I recommend learning from others who are better than you, and if you don't like myself theres so much free stuff online that can help you learn the skills it takes to make 10k+ per month in sales.
