So with the end of the year fast approaching, I am done with new accounts for the next 12 months. I thought it would be interesting to see what people have done for themselves over the course of the year.
Quick background... 3 years ago, my highest limit was $3,000, and that was a store card. I only had a couple Majors, and they were all small limits. With the help of MyFico, I've been able to pull myself back to the point of getting regular 5 figure SL and get to the point where I can start cancelling unproductive cards without effecting my score. Thanks, everyone!

Starting this year I had a single card account with a $1K limit (Synovus). Since then I've acquired everything in my sig, and I've collected enough rewards to send me and my wife on an epic vacation next year.
2017 was the year I finally (kind of) figured out how to properly handle credit. I had primarily used my debit card for the last 5 years, after buying my house, thinking that I wouldn't be tempted to overspend because I track everything (daily...well...hourly...who's kidding...every minute...) Then I had my card compromised by hackers in Jordan. Whoops, my bad, that'll never happen again! Bank cleared the charges, I was refunded in 2 business days and I had a new card overnighted. Life is good. Then my card is compromised by someone in the UK, who was trying to buy something I would've bought had I been in London at the time! Second time?! Shame on me. Bank clears the charges again. But now, almost every debit I attempt outside of my normal spending is rejected! I call the bank, they approve my card for use for that business day. Umm. I couldn't live like that. So then I wised up.
I paid down my debt to 8% revolving UTIL. My scores jumped. Now I have not been the savviest at figuring out what cards work best for me, but I can say as we head towards 2018 I can comfortably garden until my US Bank 0% APR expires.
Started the year with mainly subprime cards, slightly over $17K CL. I've opened prime accounts, closed many of the subprimes. Of the $17K+ I started with, I parted ways with $11K. When I went to garden at the beginning of November my CL was approximately $60K.
As much grief as Capital One gets around these parts, I received a better than expected CLI. Citi has been showing me some love as well. So I will say that those banks are very good to you if you give them the spend. And given a couple of situations with each bank this year, they were exemplary in their response. I will not leave either bank (voluntarily) 
My year end revolving is $88.5K.
I have gotten to this point after over 2 decades of poorly navigating credit, thanks to the MyFico community. For anyone who is in a rebuild, or at the finish line, this community is THE BEST source of information around.
