Sincerity is something of the heart, and it is pertinent that we are sincere in anything we do because that is another virtue that will make us persevere.
No matter what you do in this life, you cannot deceive yourself. One day you will have to sit back and ask yourself some important questions, and you will have to give yourself the correct answers to those questions.
You can lie to people but not to yourself, and the truth you realise by yourself sinks better than the one you are told.
It is better you get the truth very early in life so that you will not have to regret it tomorrow.
Our hearts hide our thoughts, and if we don't guard them well, it may be very hard for us to be truthful to ourselves. If we always shift blame onto other people or onto other things without taking up responsibility for whatever is happening to us, then we will have to pay the price of suffering for what we did not take into consideration.
The heart of sincerity makes us get what we want at the right time. If you know that what your heart thinks is not what your mouth is saying, then it will be very hard to act correctly.
