#30: Keep it to Yourself
Such an important tip that is so often overlooked. I don’t know if this can even really be considered a life hack as it’s more a function of common decency but I suppose there are very many people out there who could do with adopting it (not looking at any of you in particular).

I guess even the best of us get carried with delight at hearing the sound of our own voice, especially when we know we are right and have the opportunity to prove it at the cost of some poor coworker’s self-esteem. I know, it’s only natural – but even so might be best to try and do it a little less.
