Here are 3 key points to increase self-confidence:
1. Tolerate reversals with a positive frame of mind. See setbacks as temporary and focus on learning from mistakes.
2. Choose your friends well. Spend time with optimistic people who believe in your potential and lift you up rather than drag you down.
3. Dwell on your strengths and accomplishments rather than weaknesses. Take pride in what you're good at while also challenging yourself to grow.
