working hard without being smart is a waste of effort, you will just be on your work for the rest of your life.
You need to be smart, a smart worker will give importance to his/her job in such a wise and perfect outcome,
always have time with the family and thinking on what is better and what is right to do.
We hunters are being smart here, that is why we are getting better in life.
by working smarter we spend less energy. and there will be more things we can do. and of course this will make our income become larger.
For sue smart worker can get more profit with ease and without getting any harm, bitcoin is very easy to get profit but if you have a smart mind, holding bitcoin can give you lots of profit as for it you will not have to work hard but you will have to plan smart as buy when you see the price of bitcoin is low and have proper planning not to sell till it gets high once again, at the same time hard working is also important but I think smart mind can get more profit than hard working mind.
