If you’re an entrepreneur who would like to be happier in your work and life, chances are excellent your first impulse will be to add something. Maybe you could exercise or meditate more? Perhaps a new career direction would solve your woes? Indeed, those are often good happiness moves, but as Harvard happiness researcher Arthur Brooks recently pointed out in The Atlantic, they are only half the happiness equation.

Yes, we can improve well-being by adding joy to our lives. But we can also achieve the same aim by subtracting misery. Brooks even links to a test that can tell you which approach is likely to be more successful for you. What practices or habits should be on the chopping block if you want to stop overlooking the subtractive approach to greater happiness? For inspiration, Brooks looks to the writings of the great philosopher and Nobel laureate in literature Bertrand Russell.

Russell, who has been coming up strangely often in my reading lately, believed “unhappiness to be very largely due to mistaken views of the world,” and broke these common misery-inducing mistakes into eight categories.

1. Fashionable pessimism

In plenty of circles these days, being grumpy and cynical is taken as a sign of depth and intelligence. This is not a new phenomenon, Brooks points out. Melancholy was all the rage in Victorian times, too. Choosing moodiness to look cool was dumb then, continued to be dumb in Russell’s time, when he mocked it mercilessly, and is dumb now.

2. Social comparison

Russell believed that “what most people fear is not falling into destitution but ‘that they will fail to outshine their neighbors,'” Brooks explains. Keeping up with the Jones is a never-ending game that can lead to lifelong discontent. And if you don’t believe the Nobel laureate, there’s modern science to prove it. The solution to social comparison, according to Russell, is to “focus on what you have and feel grateful.”

3. Envy

Closely linked to the above mistake, envy is the condition of feeling bad because someone else has more than you. Russell’s proposed this cure for envy: “Whoever wishes to increase human happiness must wish to increase admiration.” Rather than suffer because of other people’s excellence, celebrate and learn from it.

4. Evading boredom

“We are less bored than our ancestors were,” Russell wrote in 1930, “but we are more afraid of boredom.” Imagine what he would have made of the smartphone era! But the truth is, no gadget or streaming service can fully save you from boredom. They can, however, distract you from essential but uncomfortable reflection and creative growth. The solution is to fight to regain your capacity to just sit quietly and notice the world around you.

5. Coping with fear

Anxiety has only increased since Russell’s day, and it remains a thief of joy. “Russell believed that anxiety is rooted in fear of ‘some danger which we are unwilling to face,'”  Brooks notes before highlighting modern science on the biological basis of anxiety disorders. But whatever the cause of your free-floating fear, not going to the effort of finding ways to tame it will make you miserable. Russell — and Tim Ferriss — suggests the best cure is forcing yourself to mentally face your fears until they lose some of their terror.

6. Senseless guilt

Should you feel guilty and make amends if you did something wrong and hurt someone? Of course, but Russell argued against a baseless sense of sin or feeling guilty just because you are doing well and others are doing less well.

7. Virtuous victimhood

Russell again feels ahead of his time with his warnings against playing the victim. “Russell was critical of what he called ‘persecution mania,’ in which one is ‘perpetually the victim of ingratitude, unkindness, and treachery.’ One version of this is what some researchers have called ‘virtuous victimhood,'” explains Brooks. Of course, sometimes people really are victims of injustice, but putting unending victimhood at the heart of your identity is a recipe for unhappiness.

8. Fear of public opinion
