Sorry man, Mining bitcoin is not as easy as you think. It's highly competitive now and people often join pool to mine. Most people I know, who has chosen to go solo, mine altcoins and then exchange these coins to BTC in exchanges.
Mining BTC is not a get rich quick scheme anymore, and it's a real business because you have to think about electricity cost, set up cost, repair cost, etc. If you don't want to mine altcoins, maybe buy and hold is a better option.
