Why do we let the things we don’t have disturb the one’s we do have?

Complaining about what’s lacking in our life can lead you to feel angry, resentful, and depressed all the time. Questioning why things come easy to others but are hard for you will keep you a state of constant dissatisfaction.
Focusing too much on the things we don’t have leads to discontent for life, and it keeps us from enjoying what’s before us now, which could be just as good, better, or you just have to change the way you feel about it.
If we start concentrating on what we have, we won’t miss what we lack as much. If we change how we think, we’ll be able to live happier more fulfilling lives.
Be grateful for the people and things that are in your life now. Stop wasting time and energy on things you may not have control over. Time is precious, time is scarce, invest it on the things that truly matter. Who knows, maybe along the way you’ll trample over all those other things you’ve longed for because they’re no longer your main focus.
