The strongest element of ISTp's personality is an inexhaustible curiosity towards the phenomena of the surrounding world. They are interested in adventure/tourism, the juxtaposition of cultures and the study of nature and architecture. ISTp's fundamental need is comfort both in material and physical areas. They aspire to a harmonious, peaceful and healthy style of life. They also have a well-developed aesthetic taste.
Another of ISTp's strong points is a good business sense. They usually only undertake projects that they feel will be beneficial to them in a material sense and they stay away from unprofitable ventures. ISTps can work very hard to achieve a goal. Their method of working is deliberate, steady and with attention to details. Usually they plan every detail of their work beforehand and prepare all necessary items before, often showing inventiveness and practicality.
One of ISTp problems is scepticism, which stems from their own experiences. This manifests itself in a pessimistic view towards their future. It often causes depression and despondency and leads to apathy, both in their personal and professional life.
Another of ISTp weaknesses is an inability to show their real feelings to others and because of this others may think that ISTps are cold and indifferent people. They try to deal with their problems alone. They can be very sensitive to lack of positive emotions from others, rude behaviour or tactlessness towards them.
