You may meet the greatest jiu-jitsu practitioner of all time, a virtuoso on the mat, a red belt with magical skills, but you must always remember that although those guys or girls may deserve your respect, they are just people. You may want to emulate your professor, master or grand master, but stop at admiration. You need to keep who you are intact, no falling or fawning over some jiu-jitsu super-star who teaches a seminar at your school. Respect not worship.
There are a lot of people that I admire, and although I respect their acomplishments, or attitudes, or knowledge, the respect I give them is no greater than the respect I give to a stranger. You should respect everyone equally and that includes the greatest masters and the most bragadocious street fighter. I must admit I struggle with this at times (especially the bragadocious people), but I always start with respect.
