ISFPs are the first to hear the different drummer. Many eagerly plunge into new fashions, avant garde experiences, 'hip' trends--some even setting the trends.
More in touch with the reality of their senses than their INFP counterparts, ISFPs live in the here and now. Their impulses yearn to be free, and are often loosed when others least expect it. The ISFP who continually represses these impulses feels 'dead inside' and may eventually cut and run. (One ISFP friend has become nonambulatory within the past few years. He will still, on impulse, leave home in the middle of the night and go to Las Vegas or wherever, regardless of the difficulties of his physical condition.)
ISFPs may be quite charming and ingratiating on first acquaintance, flowing with compliments which may (or may not) be deserved. On other occasions, the same individual may be aloof and detached. Some ISFP males are fiercely competitive, especially in sport or table games, and may have great difficulty losing. This competitive nature, also seen in other SP types, sometimes fosters 'lucky,' 'gut' feelings and a willingness to take risks.
Organized education is difficult for the majority of ISFPs, and many drop out before finishing secondary education. Their interest can be held better through experiential learning, at which many excel. ISFPs will practice playing an instrument or honing a favored skill for hours on end, not so much as practice as for the joy of the experience.
