Here are 12 habits that can cause unhappiness, all of which can be avoided.
1. Chronic Complaining
Happy and successful people do not complain much. On the other side, it seems that chronic complainers always have something negative to say… even when those around them are happy! The bottom line: we all have different circumstances that we are given in this lifetime, but in the end these circumstances are ours – fair or unfair, wanted or unwanted. Instead, seek solutions to problems instead of complaining, which leads to nowhere.
