When they meet for the first time, ISFP people may be very likable, very ingratiating, and will say some true or false compliments. But the next time we meet, the same person may seem cold. Some ISFP men are very competitive, especially in sports or table tennis. It may be difficult for them to lose a game. This nature-competitiveness, also exists in other SP types, makes them feel "lucky" and take risks.
Extended data:
ISFP people are as confused as INFP people, but INFP people are more imaginative than ISFP people, and have more pursuits in poetry, prose and philosophy. However, ISFP people generally don't want to write books on these aspects, or even talk about them. They want to live a real life.
Because people of ISFP type live completely in middle age, they often have no extra preparations or plans. They are excellent short-term planners. Because they are fully engaged and enjoy the experience, they will not continue to sprint to the next goal, so they feel relaxed about finishing the work.
