It really hit hard. Excuses are really very easy to make and then to accept them in short run but for long run they actually harm us and our growth is hindered. One more thing is that once we get used to it we just find it easy to make excuses every time when we are not in a mood to do anything but in actual making an excuse to yourself is really stupid, you just harm your own self and don't even know the fact.
It's not like we can live without making up an excuse, excuse is somewhat important to us but in those cases where it has to be made for our own good. Like making up an excuse to go out for a party when we are working, rather to prioritise least important thing that's going out for just party!!
