Always be mindful of the way you talk to your children.
Sweet, encouraging and positive words from the parents help in building a good self esteem for the child. The child feels positive and confident with these words, and is encouraged and motivated to rise high.
On the other hand harsh words, criticism and negative thoughts projected on the child, builds a low self esteem for the child. The child does not feel confident and doubts all their decisions. Such children will have a great difficulty in standing up to the world for their rights, and always feel doubtful of every work they do. They do not give their 100% to any task and so can move towards failure easily.
