Using your subconscious mind to create wealth is possible provided you first believe in it and second, learn it from those who have employed this simple but natural way.
I will first address the believing issue. Why your subconscious mind needs to be used in the first place to create wealth? After all, you say you work and earn but that is not what you would call wealth-right?
Wealth is having a little more than you spend for yourself and spend the excess to help others. If you don't believe in helping others with your money, then, you would never create wealth. No exception!
There, I have driven my first point. Your belief that your hard earned money is only for yourself is so very strongly embedded in your subconscious mind. Now, even if you now want to reprogram it, it is difficult without the changing your long held belief.
So, what you have to do to reprogram your subconscious mind to create abundant wealth?
There are various methods to change your belief like mirror technique, card system, auto suggestion and affirmations.
