Credit costs nothing to give and a lot to steal. People remember both.

Saying whose idea it was takes four seconds and subtracts nothing from you. Quietly taking credit feels free in the moment and then sits in somebody’s memory for years. People keep an unusually accurate ledger about this, and reputations get built on it far more than on talent. The cheapest reliable way to be well thought of is to name the people who helped.

In the next thing you hand in or present, mention one person for something they contributed. Do it where others can hear rather than privately. Watch what it does, both to them and to how people deal with you afterwards.
