Be positive, not negative. Be truthful, not deceitful. Be honest, not bogus.
Removing negativity is a good reason to be happy.
However, if you are going to work every day you receive a lot of negativity there which is sometimes difficult to be removed during your day.
Yes, I do understand that it's quite difficult to avoid negativity since it's a part of everyday life when interacting with other people which you don't have any control over.
But I do believe in the mindset of looking at a glass that's half-full rather than saying it's a glass that's half-empty because there's always pros and cons to every situation no matter what the problem is all about.
And this mindset throughout the years has greatly helped me overcome a lot of problems, to overcome a lot of unhappiness, aside from trying to focus on still trying to achieve my own personal goals.
