Hello,

One of the reason can be that you're under-confident, matlab aapmein aatma biswas ki kami hain, agar aapko stress feel hota hain, toh yeh ek karan ho sakta hain ki aap apne yogyata se kam kaam kar rahe hain, agar aisa hain toh aapko yeh janne ki koshish karni chahiye ki aisa kyu hain, aap jab ek course itne saalo se kar rahe hain toh aapka toh us course mein interest hona swabhabhik si bhaat hain, aur kewal yehi nahi aapko toh puri tarah se apne aap par biswas hona chahiye, agar aapki theory ki knowledge thik hain toh aap apne aapko ko prerit kijiye, kafi waft agar hum self-talk negative karte hain to hamare atma biswas kam ho jata hain, aap in sab cheejo par dhyan dijiye or dekhiye kuch badlao aata ki nahi.
