The key to successful investing is to have a diversified portfolio.
Remembering that I'll be dead soon is the most important tool I've ever encountered to help me make the big choices in life. Because almost everything - all external expectations, all pride, all fear of embarrassment or failure - these things just fall away in the face of death, leaving only what is truly important.
Life is short, and it's up to you to make it sweet.
In investing, what is comfortable is rarely profitable.
