At any milonga there are always a few dancers that catch everyone's attention. Their dancing is superb; their lead and follow is effortless; their musicality is outstanding.
And then there is everyone else. They are the dancers whose style is not particularly noteworthy, whose lead and follow is adequate, and whose musicality at least shows that they are listening to the music.
It is not necessary to be the best. It is not even necessary to be the best you can be.
It is OK to be average. Most people are. I would much rather dance with an average dancer who is seriously into sharing the experience than a superb dancer who is seriously into his own dancing.
It is OK to love Argentine Tango without being fanatic about it. Passion is intoxicating, it is true - and Argentine Tango can certainly inspire intense passion.
But it is also Ok to merely enjoy Tango. It is OK to dance Tango without spending all your excess hours and dollars on Tango classes and lessons. It is OK to relax, be yourself, and enjoy interpreting the music in the arms of a congenial partner, without feeling inadequate because you are not one of the best dancers on the floor.
A very wise Tango dancer once said "Competitive Tango makes as much sense as competitive kissing". Striving to be the best at Tango is kind of like striving to be the best at sex - or meditation. There is always more to learn, but if you allow what you do not know or cannot do to spoil the pleasure of the moment, you have missed the point.
Once you have learned the basics of floor-craft, and how to lead and follow comfortably, you have all you need. Two average dancers can love the dance together just as well as the best dancers on the floor.
So dance your own Tango, based upon your own desire, ability, and resources. It is your Tango. Enjoy.
