Three mistakes those are common in our everyday lives

1. Wasting time.

2. Talking about matters that don’t concern us, matters that are none of our business.
“From the goodness of one’s Islam is leaving alone that which does not concern him.”

3. Being preoccupied with trivial issues. Listening to rumors, predictions, and gossip are three common examples. Having these characteristic results in paranoia, anxiety, and a lack of purpose in life.

So Allah gave them the reward of this world, and the excellent reward of the Hereafter. (Qur ‘an 3: 148)

My Guidance shall neither go astray, nor fall into distress and misery. (Qur’an 20: 123)
