Short-term pain or long-term pain?

Been thinking for so long... now I think it is too late for any reversions... Anyway habits kills people off. Once habit slowly integrate into your subconscious, it would be too late for any changes. Especially with habits so strongly integrated with your emotions, how do you go along and stop that habit? Should I continue with the path I had chosen long ago? Should I change? How do I change? guess it's too late. Pessimism kills people off...
