Our life wants to be in a balanced state.
Something good in you is balanced by bad in you.
Similarly, Happiness is also balanced by sorrow and vice-versa.
Otherwise, you will not learn the art of living the life.
If you are worried about your bad qualities, search for your good qualities and feel proud on them.
Even a coin has two sides, and both are supposed to be also.

If you are failed today or someday, don't grieve.
You met failure only because you had achieved success someday which is to be balanced today. If you didn't achieve then you are supposed to achieve the success in future to counterpart this failure.
Be happy, and admit your mistakes learn from failure.

This is applicable in all steps of life like education, relationships, tasks, job, etc.

"Anything losses comes in another form"
And, this form is the one you deserves truly as per God's grace.
Surrender yourself to the almighty, surrender yourself to the Lord.....
