Instructing is not for everyone, some people have the aptitude and people skills, others don't. I did a bit of instructing, not much. Started flying VFR 135 at 500 hours, built time anywhere I could, full time 135 the day I hit 1200. I do currently have a CFI/MEI, but I don't use it often. Got around 8000 hours and 8 types, so it can be done. Just keep plugging away.
