Some get it just after a trial, others many trials. Always remember that your case or situation might be different and you might fall into the harder category of individuals.
Don't even think of stopping if it didn't work out the first time, just like some did, it is okay to ask questions, ask for help. It is okay to get mad and angry sometimes too as to why things seem harder for you to achieve. But in whatever you do, don't quit or stop working.
I agree, if we don't have 2 million in the bank we shouldn't be stop to work. We never know what the future is going to bring and having a fixed income we receive every month is very important. I think only a lucky few off us will ever manage to get free and stop working before retirement. Which doesn't mean that trading alt coins from home isn't a job.
