Fulfilment is found only in fitting into the slot where you belong. Although it may not be financially rewarding at the initial stage, the financial gains would certainly come the more you grow and develop in that niche.
You only need to be patient. You need to look at the big picture. Most people, especially the youth, consider the immediate picture and jump ships so frequently. Thus, they subject themselves to a life of frustration and unsettlement. You can only find peace and fulfilment by filling your own hole (in career, business, marriage, ministry and so on) or answering your own calling.
