Be happy with whatever we have achieved until now.
Wish for a better tomorrow but at the same time try to be happy with the present achievements.
Happiness and contentment should not be based on external factors. It should be always internal.
Scope of improvement in life does not mean we have failed in life until now. Be proud of what we have achieved until now and try to improve upon it.
Stop drowning in the well of self-doubt. Love ourselves for the way we are.
