What kept you from obtaining your goal this season?

This was my first season and I really wanted to hit Gold, alas, I did not. I managed to get as far as Silver I from Bronze IV, but hit a road block and all but quit ranked at the end of the season. I started playing normals more to learn different roles since I mained Jungle all season. The biggest issue that kept me back was the fact I was almost useless out of the jungle, so when I didn't get my preferred role I would be horrible on everything else. I could not play top at all for the most part this season because I didn't know the champions kits who usually go top and would usually feed. My mid wasn't terrible, but my champion pool was (and still sorta is) limited. My ADC was fine if I could farm or had a really good support, but if it was a hard lane I usually lost. My support was never horrible, but it definitely was not as strong as it could be. I've been learning more roles over the past month or so by buying new champions and playing normals (draft). Of course, I had a lot of bad teams during my time, but the true limiting factor was myself. This next season I plan on hitting Gold since I can now play more roles far more effective and regardless of what I am on, I can make an impact. I'm curious to hear what other people found to be a limiting factors that kept them from their desired rank.
