ຄວາມຝັນກັບຄວາມຈິງມັນຕ່າງກັນ

when i study in grade 8 of secondary school, i think that there is not a lot of time to decide what major i will study? because it is a good preparation, emphasize to the subject that concern with that major when i graduate from high school. at first i think i will study about IT ( Information Technology ), because that time IT is a new major but, when the time pass my mind change, from wanting to study IT i turn to interested in Medicine it mean i want to be a doctor, because doctor is a person who work helping people, take care of sick people and if i study medicine i will be able to take care of my family like parent, grandmother, sister, brother, etc... when i graduated. so, during the time i was in high school from grade 8 to grade 12 i focus on the necessary subject for learning medicine such as math, biology, chemistry
