Quitting isn't a solution but rather an excuse for someone to take because they are afraid on facing up risks.
It's okay to quit and if it can be a solution. Trading doesn't suit everybody but only a few that wants to take risk and can bear it.
What you've said can be a personal motivation to those aspiring traders and if they find to give up but still sees themselves to be a trader, they just need to be lifted up and reminded a bit of what their goals are.
Well, not everyone is good at trading, so if you feel like you don't really know, or it's hard to trade, and find a job that makes it more comfortable, it's fine to leave.
however, the comfort of each person is different. if you feel unable to do something, and it makes us depressed, then it is better to look for things that make us more comfortable than continue to be there. there are still many ways to make money besides trading, such as airdrops, or other things. Each benefit offered will be different as well as the risk.
