Life on board a pleasure steamer violates every moral and physical condition of healthy life except fresh air. - It can be a dog's life. [With George Bernard Shaw]
One is to fight and makes strides (etc.) for space to remain. One often has to fight, fight for psychological space, for example.
And a tree has no chance of winning unless it is shielded from many sorts of attacks by its bark. So the right to defend oneself is natural too. You may find it fit to keep your guard as you fight for such as psychological space and better over-all conditions in life.
Also, try to get adequately self-confident and with a natural liking to yourself. If you have that deep and fit self-confidence, you may gain unprecedented perseverance among other good things. Mind that some things are acquired by stages.
There are risks and costs to a program of action. But they are far less than the long range risks and costs of comfortable inactions. [John F. Kennedy]
A boss creates fear.
Bossism creates resentment.
Bossism makes work a drudgery.
