What’s the right way to think about life to have better life? I don’t get why I worry about past and so many opportunities missed to have better life.

If you think of those you miss, and your times with them, within a fast world you will miss many chances in opportunity. But I'd miss parts of my life if I didn't see the love of people before...

That sounds a lot like anxiety. It may help to see a therapist to learn ways to reroute the brain.

Realizing you're still missing opportunities due to past missed opportunities. Will you regret this tomorrow? Probably

Help someone in need today. Double the rewards for not living in the past

learn from your mistakes and do best you can with what you have. do not beat yourself up, shrug it off and keep trying. find someone more successful and follow their example

Unfortunately if we want a better life we have to work for it.. thats how life is for most of us..
