Treading water, help me scale!

Warriors,

I find myself in a strange situation. I consider myself somewhat successful at IM and I am absolutely thrilled that I have been able to depend on it for some - albeit nothing grand - extra income.

Yet for as thrilled as I am that I have some success here, the more usual feeling is frustration as to why I can't scale and grow this larger!

Traffic and earnings, last three years, traffic is 70% organic/30% paid:

2011
unique visitors: 13968
earnings: $1258

2012
unique visitors: 14321
earnings: $3746

2013
unique visitors: 12428
earnings: $5216

So, as you can see, my traffic is actually a bit less in 2013 than the two previous years, yet because I am adding customers my business has grown. Additionally, 2013 was my best year for new internet sales despite the lower traffic. So things are headed in the right direction, just at way too slow of a pace for me.

I have struggled to get over that roughly 1000 uniques a month threshold for sometime and I know if I do I will start to make some really good money.

Can anyone offer me some advice to turn this into a powerhouse? I feel I am on the brink but I rack my brains trying to quickly figure out ways to increase my traffic and sales.

I hear about hot shots making this kind of money within six months or a year of starting IM and here I am with years of experience (been in it a lot longer than the three years shown here) and I am struggling to take this to the next level. I think the stage is set, what is next though?
