Thanks for sharing your story. I am in your current position right now and I also fell in love with Buffer. The 3-month rule was also working against me and I thought about reapplying 3 months after some usage but stopped midway through.
Your post has inspired me to try again. Not only for Buffer but for other positions that are also “dream jobs”. Love to see how hard work has pushed you to a new level of awesomeness!
