Self development is the process by which a person's character or abilities are gradually developed. The best investment one can make on him or herself is self development. It's always that drive and hunger to be better than you were yesterday. It's not necessarily an educational certificate but it could range from skill acquisition, improvement in social and moral conduct or even participation in community service.
No knowledge is wasted. Self development should be encouraged and cultivated as this plays an integral role in nation building.[www.articles.kingjova.com.ng]
