Having someone endorse you is nice. They are saying, "This person is worthwhile. I know them and so should you. They have integrity, are trustworthy and will add value to your life. Because you know and trust my judgement, you can transfer it to this person."
Endorsements are gifts, not to be taken lightly. Never to be taken for granted. Two reputations can be smeared. Someone else lending credibility to us for free because they believe in us.
A good thing to receive. A good thing to give forward.
