Life gives us opportunities, again and again, it's ultimately on us that how we take it.
Failure in CA is not uncommon, we all know. Success will come if we keep on trying.
There will be bad days and good days. Make sure you do as much as you can on your good days that you don't have to worry about your bad days. Practice hard; practice as much as you can.
There will be people who will put you down through their words, through their taunts, but it's on you that how you are going to take that all.
It's on you that what things you prefer.
The only way up is not to give up. Be strong enough to bounce back.
Life is gonna test you at every step. Accept those challenges and work hard to overcome the hurdles that lie in front. You can't win by complaining about the hurdles that are in front. You got to make an effort to cross those hurdles efficiently.
Its ok to be disappointed but don't make this disappointment your home. Don't start living there. It's fine to be a visitor in the home of disappointment once in a while as it gives a reality check but move away from it as quickly as possible.
You are gonna face every difficult situation in CA course. So accept those challenges and let them make you strong.
When you overcome this all, the biggest achievement will be that you will be free from the fear of failure in life.
All the best.
