Work for your own money, nobody owes you anything.
Yes we dont owe them what we achieve. But I think if you know to yourself that you're somehow capable to lend, especially if this particular person is close to you (a family member) then if its me I dont see any problem with that.
Though its really satisfying to earn money through our own capital and hardwork. Because it doesnt necessarily mean that we need huge capital as a beginner, any amount will do, what matter is what you learn through that experience. Money is not hard to earn if you are hardworker and striving to get it.
You make sure the person to who you lend money to is a person who will is also capable of paying. Otherwise, you'd lose a friend and money in the end. Relationships can go wrong in a very unexpected way and it's always about trust that makes it sour. When money is part of this relationship, you may have to consider it a business relationship. No more than that.
