I read it somewhere, that for human being to do anything consistently well at subconscious level, it needs 10 yr or 10,000 hours of work.
That doesn't mean you can't be profitable trader before that.. It depends on YOU,
on how much effort you are putting in, and how fast you can change your wrong trading habits and improve yourself.
If you learn it correctly, then in 1yr to 2 yrs of committed and well directed effort , you might be able to end positively on monthly basis. Otherwise, it is also quite likely that till next 3 yrs, u are searching for holy grail method of 100% successful trading and getting confused with indicators..
All the best.
