I'm no longer a leader, but I've lead two clans for over an year, each.
Reign of Elites
: I was a co-founder/Deputy Owner of this clan for a year and half, back in 2011. A few of my old friends and I had just left another clan due to excessive drama, and decided to create this clan. It was successful, we peaked at around 350 members, and Tier 4 Citadel(We started it late) in just 2 months. I was a warring leader, and that was the main reason I left. I was inactive during a JCUP match in 2012 and the owner got angry at me for not leading a war in JCUP. This led to a debate/argument within the clan's council. I was demoted and eventually left due to unfairness.
SoulBane:
I was a Deputy Owner of SoulBane for over an year. I joined SoulBane in late 2012. I had a preference for warring back then, and this was my best choice since it's ranked #1 in F2P Rated Clan Wars. I quickly climbed the ranks in this clan, but the real journey began when I was ranked from a General to Overseer and then Deputy Owner. The old leaders had retired and became inactive. My co-leaders and I helped the clan to become active again and give it a new motive to increase the number of clan members. However, after a few months, my co-leaders began to slack and concentrate more on their xp gains and other games. I was left alone to lead the clan through a 7 month period, while working on my max cape and Comp goals. After that 7 month period, the clan was in a good state and thriving, so I decided to rank up new members for the council. Ranking up these people created an image of me being a biased ranker, and that led to a few arguments between a few admins and me. And this led to a few members of the council and me retiring and eventually leaving the clan in December.
So, overall, it was a enjoyable and stressful experience being a clan leader. Currently, I'm not aiming to being a clan leader again as I have too many goals in real life and RuneScape.
Good luck to all leaders!
