Briggs test said I'm an ISTP

A few years ago I did this test and it said I'm an ISTP. Personally I feel a bit skeptical on this matter because I think everyone has a unique personality and therefore couldn't be classified in this way (Meyer Briggs test).

Similarities between ISTP and me

• Firsthand experience is good
• troubleshooting is a good
• normal socializing is not good
• changes in interest every so often
• gives people a bad impression sometimes
• I like doing my own thing
• bored
• I think about right now more than later or in the past

ok guys

Now that I've reread this after around 3 years of not doing this test, I find no differences between me and the ISTP personality. Thanks for reading I guess.
