31 Business Lessons You Usually Learn The Hard Way is the name of an article I saw that intrigued me. I would rather learn things through the experiences of others than by hard experience. Here are a couple of the lessons - the rest are in the article.
"The only way to get other people to care about you is to care about them first." This reminds me of so many Zig Ziglar quotes that instruct me to put others first and to help them and then it comes full circle.
"The difference between success and failure is just a decision to keep trying." Perseverance - a large subject but one worth spending some time with. I am always surprised at how quick people are to give up on trying to do something or finish something. An extra question or an extra call can make all the difference.
"Negativity isn’t reality. Not for you. Not for your critics." Being negative is easy and spreading negativity is easy. Many, if not most, of the most successful people I have ever met see the good in people and situations. Being negative just hurts me and doesn't help anyone else.
Not all 31 lessons are great but they are worth a quick read.
