Enthusiasm is the best protection in any situation. Wholeheartedness is contagious. Give yourself, if you wish to get others.
From time to time, I'll look back through the personal journals I've scribbled in throughout my life, the keepers of my raw thoughts and emotions. The words poured forth after my dad died, when I went through a divorce, and after I was diagnosed with breast cancer. There are so many what-ifs scribbled on those pages.
However mean your life is, meet it and live it: do not shun it and call it hard names. Cultivate poverty like a garden herb, like sage. Do not trouble yourself much to get new things, whether clothes or friends. Things do not change, we change. Sell your clothes and keep your thoughts.
