The result? Those persons are now broke , divorced from their wives and are miserable right now. What I want to say is that a strategy can only work for a very short amount of time and not in a continuous way.
In my opinion it is unfair to easily conclude that making strategies are pointless because at the end of the day you will lose. Strategies, even if it is as complicated as having mathematical calculations or as simple as a smart guess, are still beneficial. If you are losing then it could be either your strategy doesn't suit to your game or the problem is within in you. I mean, you will not really have a bright future even how effective your strategy is if you are a "One day rich man" or uncontrollably spend your money to buy not so important things in short, not a wise money holder.
It is important to know what we would like to do our life not just for today or tomorrow but for the long term goal. Many were not properly oriented on how to be wise in budgeting, spending too much more than of what we've got will end up nothing.
It just like of what we do in gambling, we need to have a strategic planning in order to win the competition but it is sad to know that gambling isn't winning all the time unlike we do in investing. Better not to be greatly involve in gambling cause it won't give more profits to us.
