"Low self-esteem is like driving through life with your hand-break on."
How fine life would be if we all felt like a million dollars 24 hours a day, 7 days a week! We would never, ever feel like we have woken up in a pit, full of self confidence lows, having the energy to just jump out of bed and meet the day with loads of enthusiasm and knowing that we are going to get through the day without worries of any kind. The sun will shine all day, with just enough breeze to keep our bodies cool. Life is good, oh so good.
NOT if you are a person imprisoned by low self confidence, it so is not. Low self confidence is a very nasty characteristic to have inside us. It makes us feel weak. It makes us lose faith in our actions and dreams. It can even stop us from going forward in our lives with relationships.
               Especially in IITs one encounters many brainiacs like themselves so its pretty hard to keep up your self confidence! 

CAUSES:

Fear
If you have a fear stopping you from performing in a specific area, all you can do to raise your self confidence, is to face the fear. You must go do what you're afraid of and break through that mental barrier. 

It's amazing how our self esteem shoots way up when we do this and realize low unfounded our fears were to begin with. 

Guilt

If you experience many guilty feelings, it will cause low self-confidence and esteem. If you've wronged someone, take action to make up for it. Apologize and ask for forgiveness. Most likely, you'll receive that forgiveness. 
You're here to live, learn, then judge yourself when it's all over. 
Did you know that many people who have experienced "near death experiences" report that instead of being judged by a greater being, they saw themselves judging and learning about their lives - a life review? 

Rid yourself of this guilt and watch your self confidence grow. 

Unrealistic Expectations
If you place unrealistic expectations on yourself, it can lead to low self confidence.Be careful when you set yourself goals. Who and what you are has no bearing on your earthly accomplishments. If you set a goal and it takes you twice as long to achieve it, so what? 

REMEDIES:
* Write down your positive achievements, all that you can remember; educations, jobs, loves and relationships (even if they ended, you still achieved them), friendships, children, 
driving licence... Look at what you already have and realize you have done rather well.
* Write down good things that others have said about you. Read through old documents from former employers or teachers that state all your strong sides. Maybe you forgot you had them?
* Make plans. Ask yourself what can be done. What can you change to make things better? Write down precise goals and write a step-by-step plan on how you intend to achieve your 
goals.
*Decision. Make a decision that tomorrow you will start dealing with the first step of your plan.

JUST REMEMBER:
"You, yourself, as much as anybody in the entire universe, deserve your love and affection."
-Buddha
