Name three strategies for Challenging the Unknown.

In my personal experience

1. Pray to Jehovah God and ask for his guidance

2. Read about experiences of other people that faced challenging the unknown and how they either failed or succeed and apply that knowledge to your own life

3. Be realistic. You need to consider the possible benefits and consequences of what you are planning to do and think how this will affect now only you but your friends and family members as well, if it's a necessary thing you need to do then go for it but if it will impact your life too much then don't risk yourself. Life, health, family, friends, etc is so much important than anything else you may want to gain or accomplish
