With gambling smart work is much in need which is the calculation and other related factors.
There is nothing called smart work. You should do that in your workplace and not in gambling or in any game of chance where the odds are against you.Quote
When it comes to hard work it is all about the learning of different strategies that are available to overcome the losses. Hard work along with smart work with respect to spending that is affordable gets success in gambling.
Totally false statement. Luck is the only thing that is need in gambling. Without luck you are doomed to get wiped out of your bankroll. If you have some skills you might do well in EV+ games but in games like dice and slots you are bound to lose in the long run. So be wise and dont gamble too much.Or just get a huge bet profit and get a new life 
Getting a new life would be better because only 1 in a million people win the jackpot and practically its a waste if time if you chase it.Do you think that every game have a jackpot? Do you think that every game has odds against you?
When it comes to hard work it is all about the learning of different strategies! Its not a false statement, its true. You learn along the way, you try to find better approach, I didn't lose and fail 1000 times, it was just found ways that didn't work. Hard work is essence, nothing without it. Nothing without nights and nights of being awake and trying, learning new ways.
For end I will just say poker! Don't look gambling trough dice and slot games, its not all about it, its fun, real games are the one where you need to think, to have attitude, to be intelligent and to outsmart others with your mind or bankroll, you choose your advantage.
