Hobbies and interest sounds same but are not..
hobbies is an activity that u do for pleasure when u r not involved in any kid of work... usually to pass ur time by not wasting it... and interest is an activity or any subject that u like and enjoy and that u spend ur free time or studying something u love the most...hobbies is something which keeps us calm and we really get into it whereas interest should be something u like it in ur own way...
now examples of hobbies can be like drawing, reading, dancing, singing etc
and examples of interest can be like science , nature etc
HOPE IT WORKS FOR YOU :)
