Fear of the unknown
Ever been in a situation were you fear for what becomes of you tomorrow I've , one thing is , situation turns and when it does one tends to lose interest, courage. Fear is terrible especially when you aren't expecting on how it turns out tomorrow . A woman is afraid of who she marries tomorrow likewise a Man, we fear if the marriage last long what will she be able to contribute, is he/she the kind who's self centered or selfish, the list goes on and on. A friend once told me, " I worry if I will ever make a good decision out of this"
pupils , students, candidates etc fear of how their result turns out after examination ...worries of the unknown. People ask questions because they worry or fear and get curious of something etc... speaking from my experience, I will say fear for the unknown is what usually occur to humans. Do not put yourself in a situation were you have to fear or worry of a certain outcome, life sometimes is unpredictable, unforeseen occurrence and time change people likewise conditions..
Everyone worries even a toddler does. It's far beyond the truth to state that childhood is the best time in your life and free of worries.
