Why is confidence important? Yeah , being confident in the real world is really important and essential for us . It helps us live a better life or get a job opportunity easily if we show our confidence when speaking with other people . I've experienced that . I've attended a job interview and I prepared a lot for it . So I always smiled and spoke confidently and fluently in the whole process . I left a good impression on the interviewer. Finally I got through this interview face to face with flying colors . You'll be more attractive to girls if you're confident when you are developing a relationship . So be confident every day . Cheers !
